Understanding Base 10 Manipulatives

The video tutorial guides students through solving an addition problem using manipulatives. The teacher introduces the problem of finding the total of four numbers: 18, 29, 36, and 17. By using manipulatives, the teacher demonstrates how to form groups of ten to simplify the counting process. The tutorial concludes with counting by tens to arrive at the correct total of 100.

What is the main question posed at the beginning of the video?

• How to multiply numbers using base 10 blocks?

• What's the total of four given numbers?

• How to divide numbers using base 10 blocks?

• What's the difference between two numbers?

Which numbers are represented by manipulatives in the video?

• 15, 25, 35, 20

• 20, 30, 40, 10

• 18, 29, 36, 17

• 12, 24, 35, 19
