Decomposing Numbers and Number Sense

Susan Jones presents a video tutorial on teaching students how to decompose numbers. The video covers four main ideas: using hands-on activities, engaging games, quick images, and expanded form. These methods help students understand number sense and different ways to break down numbers. The video includes practical activities like 'Magic Bag' and 'Shake and Spill', and offers free resources for teachers. The tutorial is aimed at kindergarten to second-grade teachers, providing strategies to enhance students' mathematical skills.

Why is decomposing numbers an important skill for students to learn?

• It is not important for early education.

• It helps them understand multiplication.

• It is only useful for subtraction.

• It enhances their number sense.

In the Magic Bag activity, what do students do with the cubes they pull out?

• They use them to build a tower.

• They throw them away.

• They sort them by color and make a cube train.

• They count them and put them back in the bag.

What is the main purpose of the Shake and Spill activity?

• To practice writing numbers.

• To help students understand division.

• To show different ways to make a number using counters.

• To teach students how to multiply numbers.

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

• Multiply the numbers together.

• Subtract the smaller number from the larger one.

• Write the numbers in the part and whole sections.

• Add the numbers and write the sum.

What is the objective of the Roll, Solve, and Color game?

• To color the entire grid first.

• To solve the number bond and color the grid.

• To find the largest number possible.

• To roll the dice and add the numbers.

How do Quick Images or Dot Cards help students?

• They are used for art projects.

• They help in memorizing multiplication tables.

• They improve reading skills.

• They encourage students to think of different ways to make a number.

What is the main goal when using Quick Images in a math lesson?

• To draw more dots on the card.

• To determine how many dots are present and how they are grouped.

• To count the dots as quickly as possible.

• To identify the color of the dots.

What is the purpose of using expanded form in teaching decomposing numbers?

• To teach multiplication of large numbers.

• To make subtraction easier.

• To help students understand larger numbers by breaking them into hundreds, tens, and ones.

• To simplify addition problems.

When using base 10 blocks, what is a possible way to decompose the number 324?

• 300 + 20 + 4

• 32 + 4

• 300 + 24

• All of the above

Which grade level is most suitable for learning decomposing numbers using expanded form?

• Third Grade

• Kindergarten

• First Grade

• Second Grade
