How to Write a Mathematics Lesson

  1. Always think about “what is it that I want the students to learn?” a. These should be your lesson objectives b. AND they should reflect what is on your assessment à You can create your assessment first so that you know exactly at what “end” you want to be, what you value, and what you ultimately want the students to know c. KUD’s: What you want your students to K now, U nderstand, & D o
  2. Then try to think of why this is important a. Is it a foundational idea in which other concepts will build? b. Does it have great historical or practical importance? c. Where is it used in the real world or how will it help the students?
  3. This “why” should lead you to how to formulate your lesson a. Have this be the starting off point to motivate the students to learn b. This should be a theme throughout your lesson
  4. ALWAYS start with something concrete that the students can relate to and grab hold of – this is your opportunity to create a “problem” so your students can become better “problem solvers” a. This is also your opportunity to spark curiosity and instill motivation: show the power and importance of math b. Hopefully this will avoid the “why do we have to know this anyway,” “what is the point of this,” and the “why should we care about this”
  5. Once you have their attention and motivation use it to empower them and teach them math! a. Think about all of the ways you can engage the students: does this topic lend itself to group work, pairs, or whole class instruction? b. Can you create enough scaffolding so that the students can be the center of the lesson (you do the least amount of talking as possible)? ALWAYS think to yourself – “how can my students understand this topic without me telling it to them?” c. Always want the students to be doing more “work” than you in the classroom (outside of the classroom is a different story)
  6. After you have created positive-­‐minded, motivated, and enthusiastic students you can move towards the abstract and practice “math problems” Figure out the importance of HW – why should they do it: practice? Extension? You as the teacher need to determine the value you place on HW. Just don’t give them HW for the sake of giving HW, make it meaningful! If you are going to assign it, and you expect your students to do it, then you better be prepared to spend adequate time on it. If you do not have adequate time, make it optional – say these are practice problems that would behoove you to do, especially if you need the practice. For a student looking in the math textbook, all of the problems look the same, so lead them in right direction of where you want them to focus their attention and energy.

EDU 556 Mathematics Lesson Plan Format Develop a problem-­‐based lesson plan that engages the students in the Standards for Mathematical Practice and promotes the learning of the identified objective. Title: [Insert text here] Grade Level [Insert text here]

  1. Lesson Overview Summarize the lesson content, rationale, and purpose (goals of the lesson) in 3-­‐ 4 sentences. How in this lesson might you...
  • Engage students in productive struggle?
  • Get students to think and make connections?
  • Provide support for each student? [Insert text here] Sentence 1: Lesson overview – what are you teaching & to whom? Sentence 2: why are you teaching it in this way? Why did you choose the activities you did? Sentence 3: What goal(s) do you hope to meet by the end of this lesson?
  1. Learning Objectives Identify the measureable behaviors students should demonstrate. [Insert text here] - List here in bullet points 3a. Common Core Content Standards [Insert text here]
    • One primary and (potentially) secondary standard(s) 3b. Common Core Standards for Mathematical Practice [Insert text here]
      • List the practices your lesson addresses
  2. Materials and Resources Identify materials and resources essential for successful completion of the lesson tasks or activities. [Insert text here] - List all mathematics manipulatives, tools, software, special paper (graph paper, card stock, etc.) and/or tools 5. Lesson Development (include time designations for each component) Outline the instructional strategies you will use to incorporate the materials and activities you have planned to obtain your objectives. Basically , what are you and the students going to be doing during class time? a. Engagement/Motivation (beginning): Describe the initial task or activity to engage and motivate students, activate relevant prior knowledge, and introduce the learning objectives. Activate prior knowledge & provide background information:
  • Determine how you will introduce the task/problem scenario (what problem(s) will the students have to solve?) – will you show a video, read a story, or something else?
  • Consider warm-­‐ups that orient students’ thinking
  • Build background; link to prior learning and to familiar concepts
  • Incorporate review of key vocabulary
  • Set task in written and oral form
  • Make sure students understand the task
  • Provide visual and real objects Be sure to set the stage for the day’s activities [Insert text here] - This should be short bullet points. - Consider the bullets list in box to the left; you should address at least four of these points
  1. Differentiation Describe plans to differentiate content, processes, context, and/or products. Identify accommodations, extensions, and/or enhancements to meet individual needs, including those of English language learners, special education students, and learners with gifts/talents. For example, strategies for English-language learners such as attending to key vocabulary, using visuals and providing opportunities to practice language are explicitly incorporated by answering the following:
  • What content and context words have you selected?
  • Where in the lesson might you place the vocabulary support?
  • What will it look like? [Insert text here] - Include specific plans for individual students as necessary – this can be creating specific groups or partners for an activity, providing different representations, or having students report findings/understandings in different ways
  1. Assessment/Evidence of Success: Describe how you will measure student performance, understanding, and achievement.
  • What evidence will be collected (consider informal and formal evidence)?
  • How will the evidence be evaluated?
  • How will you know who understands what? [Insert text here]
  • List at least two ways you will assess students’ learning.
  • How will you know what your students understood?
  • Discuss whether evidence will be evaluated; if so, how? EXAMPLE LESSON PLAN: Centipede’s 100 Shoes – Repeated Addition Lesson Plan Grade Level 2
  1. Lesson Overview While reading Centipede’s 100 Shoes students will find the total number of shoes the centipede has at different points in the story using strategies of repeated addition. Students can work together in pairs to draw pictures corresponding to the story (or use other strategies) and then create the repeated addition equations to match each picture. The goal/purpose of the lesson is for students to use, understand when and why to use, and practice repeated addition.
  2. Learning Objectives
  • Use repeated addition to find the total number of objects 3a. Common Core Content Standards 2.OA.C.4 Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and up to 5 columns; write an equation to express the total as a sum of equal addends. 3b. Common Core Standards for Mathematical Practice
  • MP1. Make sense of problems and preserve in solving them
  • MP2. Reason abstractly and quantitatively
  • MP3. Construct viable arguments and critique the reasoning of others
  • MP4. Model with mathematics
  • MP8. Look for and express regularity in repeated reasoning
  1. Materials and Resources
  • Centipede’s 100 Shoes by Tony Ross
  • Chart paper
  • Markers & pencils
  • List of animals/insects in the book
  • Pictures of animals/insects in book for students to glue onto papers
  • Glue
  • Unifix cubes, toothpicks, chips, or other objects students can use to model legs/shoes
  1. Lesson Development (include time designations for each component) a. Engagement/ Motivation (beginning): About 10-­‐15 minutes:
  • Students pick up warm up worksheet as them come into class
  • Question: “What is the total number of shoes in our classroom?”
  • Tell students they can solve in any way – words, pictures, manipulatives, equations, etc.
  • Answer any clarifying questions as needed
  • Put directions on the front board: “Take warm up worksheet from front and solve the problem in any way. When you are done, find a neighbor to discuss your solutions. How do they compare? Did you get the same answer? Explain how you got your answer.”
  • Circulate around the room to check-­‐in on students – see what they are doing and listen to their conversations About 5 minutes:
  • When most students are done sharing strategies with a neighbor or are in the process of sharing the strategy (have already completed the task), have a few volunteers share their strategies (if found different solution strategies while walking around, can ask those specific students)
  • If repeated addition does not come up, show students this strategy as if I was a student sharing my solution strategy
  • Have students evaluate this strategy (as they evaluated each of their classmates’ strategies presented) and start to see its efficiency b. Instructional Procedures (during): 5 minutes:
  • Introduce story: “Today we are going to read Centipede’s 100 Shoes. How many feet do you think the centipede has?” (allow students to share responses)
  • “Actually, according to the story, a centipede only has 42 legs. How many legs would be on each side of his body? How do you know?” (again allow students to share responses)
  • “This centipede bought some shoes, but decides he does not want to wear them and gives them all away. We are going to try to find out how many shoes the centipede has left to give out and who he could give them to.” 5 minutes:
  • Read story, stopping at sticky note (p.22) 5 minutes:
  • Give directions for activity: “Your job is to figure out how many shoes the centipede has already given away, how many he has left to give, and who the leftover shoes could be given to. You will work with a partner and show your thinking on the chart paper. You can show your thinking in any way, but you want to be efficient and accurate in your work. What could be the best way to show your work?” Have students fold paper into sixths and glue an insect picture at the top of each section to designate it. 15 minutes:
  • Student work time – circulate to groups and observe thinking: o Which students are able to articulate thinking? If a student is not able to articulate thinking, ask questions like “what did you do here?” in succession (at each step –
  • For students that need an extension, ask them to write the matching multiplication sentence under their repeated addition sentence. If needed, provide more difficult situations for repeated addition like finding other combinations of animals/insects that could take all of the centipede’s shoes.

Assessment/ Evidence of Success:

  • Student work on posters will be evaluated informally. This will show who understands the concepts as we work through the 4 insects. If students get stuck, I will be circulating around to help them (as described above) and looking for: o Do the repeated addition strategies match the animal? o Did students correctly add to find how many shoes? o Were they able to find out how many were left?
  • Student sharing of strategies will be evaluated informally: o Were students able to explain what they did? Did it make sense? o Were students able to explain why repeated addition is useful?
