In this lesson, students represent composition and decomposition of numbers to 5 using pictorial and numeric number bonds.

In this lesson, students represent number bonds with composition and decomposition story situations.

In this lesson, students model decompositions of 6–8 using linking cube sticks to see patterns.

In this lesson, students represent decompositions for 6–8 using horizontal and vertical number bonds.

In this lesson, students use the 5?groups to represent the 5 + n pattern to 8.

In this lesson, students model decompositions of 6 using a story situation, objects, and number bonds.

In this lesson, students model decompositions of 7 using a story situation, sets, and number bonds.

In this lesson, students model decompositions of 8 using a story situation, arrays, and number bonds.

In this lesson, students decompose the number 6 using 5-group drawings by breaking off or removing a part, and record each decomposition with a drawing and subtraction equation.

In this lesson, students decompose the number 7 using 5-group drawings by hiding a part, and record each decomposition with a drawing and subtraction equation

In this lesson, students decompose the number 8 using 5-group drawings and crossing off a part, and record each decomposition with a drawing and subtraction equation.

In this lesson, students model decompositions of 9 using a story situation, objects, and number bonds.

In this lesson, students model decompositions of 10 using a story situation, objects, and number bonds.

Students will work with partners to put chips into a bag of a certain number between 11 and 30. The chips will be a different color on each side. Once the chips fall out of the bag the student will see different combinations that make the same number. They will record 4 combinations for each number. This lesson was developed by NCDPI as part of the Academically and/or Intellectually Gifted Instructional Resources Project. This lesson plan has been vetted at the state level for standards alignment, AIG focus, and content accuracy.

The purpose of this task is for students to find different pairs of numbers that sum to 9.

This is an article explaining a number sense activity that utilizes the book "Room on the Broom". The activity uses number-valued animal cards to allow students to follow the story and explore the decomposition of numbers into equal or unequal parts (and compose back to a whole), and compare sets using the attribute of numerosity. Downloadable animal cards are available.

In this Khan Academy interactive, students will decompose numbers less than or equal to 10 into pairs.
