Anchor Charts

The Importance of Anchor Charts

These charts are created as a result of a joint effort between the teacher and the students. They

are not created ahead of time. As the teacher models the strategy, it is recorded using a variety

of media (chart paper, journals, electronic presentations), along with any tips or advice to help

students remember the concept.

Once the lesson is complete, the chart is placed in a visible convenient location so the students

can access it at any time in order to gain support independently. Some anchor charts are on

display all year long, while others are only displayed during the current unit of study.

The resources you will find in this document are intended to be a springboard for your own

creations. They are simply examples of how you could work together with your own students to

present important concepts to further their thinking and support them as they work to understand

the material.

*For more information, please refer to the article “Hook and Hold” by Jennifer R. Brown. This

can be found in Teaching Children Mathematics (Vol. 21, No. 1, August 2014).

An anchor chart is a tool used to facilitate discussions and record appropriate math

strategies. These charts are created during the instruction portion of the lesson. They

are in place to “anchor” student learning to appropriate practices.

OPERATIONS AND ALGEBRAIC THINKING

NC.4.OA.

Interpret a multiplication equation as a comparison. Multiply or divide to solve word problems involving multiplicative comparisons using models and equations with a symbol for the unknown number. Distinguish multiplicative comparison from additive comparison.

DESCRIPTION

An anchor chart is a great way to help students see scenarios where the unknown portion of the problem changes and how the required math changes as a result.

OPERATIONS AND ALGEBRAIC THINKING

NC.4.OA.

Interpret a multiplication equation as a comparison. Multiply or divide to solve word problems involving multiplicative comparisons using models and equations with a symbol for the unknown number. Distinguish multiplicative comparison from additive comparison.

DESCRIPTION

An anchor chart uses bar models to help students make sense of word problems so that they can identify the unknown and the action required to find its value.

OPERATIONS AND ALGEBRAIC THINKING

NC.4.OA.

Solve two-step word problems involving the four operations with whole numbers. ● Use estimation strategies to assess reasonableness of answers. ● Interpret remainders in word problems. ● Represent problems using equations with a letter standing for the unknown quantity.

DESCRIPTION

This anchor chart poses different division situations and calls for students to determine what to do with the remainder (drop it, use it, round it). This would be a good introduction to a lesson where students have to sort word problems into these categories.

OPERATIONS AND ALGEBRAIC THINKING

NC.4.OA.

Find all factor pairs for whole numbers up to and including 50 to: ● Recognize that a whole number is a multiple of each of its factors. ● Determine whether a given whole number is a multiple of a given one digit number. ● Determine if the number is prime or composite.

DESCRIPTION

By working with your class to generate an anchor chart like the one below, you can help students to develop and retain definitions of the important vocabulary associated with this standard.

OPERATIONS AND ALGEBRAIC THINKING

NC.4.OA.

Generate and analyze a number or shape pattern that follows a given rule.

DESCRIPTION

This anchor chart displays both number and shape patterns. Function tables are also a great resource for anchor charts because they help students organize their thinking.

NUMBER AND OPERATIONS - BASE TEN

NC.4.NBT.

Explain that in a multi-digit whole number, a digit in one place represents 10 times as much as it represents in the place to its right, up to 100,000.

DESCRIPTION

This anchor chart uses a place value chart to demonstrate the value of each place as increasing by 10 times.

NUMBER AND OPERATIONS - BASE TEN

NC.4.NBT.

Add and subtract multi-digit whole numbers up to and including 100, using the standard algorithm with place value understanding.

DESCRIPTION

This anchor chart displays four common strategies for adding. This chart was created with students during number talks. It is intended to encourage students to try an alternative strategy and help students correctly identify addition strategies as they use them.

NUMBER AND OPERATIONS - BASE TEN

NC.4.NBT.

Add and subtract multi-digit whole numbers up to and including 100, using the standard algorithm with place value understanding.

DESCRIPTION

This anchor chart displays four common strategies for subtracting. This chart was created with students during number talks. It is intended to encourage students to try an alternative strategy and help students correctly identify subtraction strategies as they use them.

NUMBER AND OPERATIONS - BASE TEN

NC.4.NBT.

Add and subtract multi-digit whole numbers up to and including 100, using the standard algorithm with place value understanding.

DESCRIPTION

This anchor chart is designed to help students see a variety of strategies for adding two two-digit numbers, including the algorithm. It is important that students see connections across strategies, and have the opportunity to choose what works best for them.

NUMBER AND OPERATIONS - BASE TEN

NC.4.NBT.

Multiply a whole number of up to three digits by a one-digit whole number, and multiply up to two two-digit numbers with place value understanding using area models, partial products, and the properties of operations. Use models to make connections and develop the algorithm.

DESCRIPTION

This chart demonstrates the properties of multiplication in kid-friendly language, along with actual examples of the properties in action.

NUMBER AND OPERATIONS - BASE TEN

NC.4.NBT.

Multiply a whole number of up to three digits by a one-digit whole number, and multiply up to two two-digit numbers with place value understanding using area models, partial products, and the properties of operations. Use models to make connections and develop the algorithm.

DESCRIPTION

In this anchor chart, there are two models for how to multiply two two-digit numbers. Both models are effective ways to arrive at solutions for multiplication. It is important when using the Lattice Model that students understand the place value of the numbers in the model.

NUMBER AND OPERATIONS - BASE TEN

NC.4.NBT.

Multiply a whole number of up to three digits by a one-digit whole number, and multiply up to two two-digit numbers with place value understanding using area models, partial products, and the properties of operations. Use models to make connections and develop the algorithm.

DESCRIPTION

This teacher created chart showcases both partial products and area models for multiplication. It also gives four different examples of how students may choose to multiply in fourth grade.
