Understanding Number Decomposition Activities

This video by Susan Jones explores four engaging methods to teach students how to decompose numbers. It emphasizes hands-on activities, games, and visual aids like quick images and dot cards to enhance number sense. The video also covers using expanded form for second graders, providing practical tips and free resources for teachers.

What is the primary benefit of teaching students to decompose numbers?

• It makes math more difficult.

• It allows them to see numbers as flexible and composed of parts.

• It helps them memorize numbers.

• It is only useful for addition.

In the 'Magic Bag' activity, what do students do with the cubes?

• They throw them away.

• They count them silently.

• They sort them by color to show different ways to make a number.

• They use them to build a tower.

What is the purpose of using double-sided counters in decomposition activities?

• To confuse students.

• To replace number bonds.

• To make the activity colorful.

• To easily show two different parts of a number.

In the 'Roll a Bond' game, what do students need to do after rolling the dice?

• Write a story.

• Draw a picture.

• Write the numbers in the correct parts of a number bond.

• Ignore the numbers.

How do quick images help students with number sense?

• By encouraging them to see different groupings of dots.

• By making them memorize numbers.

• By confusing them with too many dots.

• By making them count slowly.

What is the focus of using expanded form in teaching decomposition?

• To replace all other forms of decomposition.

• To make math more colorful.

• To help students see the value of each digit in larger numbers.

• To make numbers harder to understand.
