Lesson 1-3 Why do we need place value (worksheets)

Worksheets teach to Multidigit

Lesson 1

Lesson one why do we need place value. This lesson is pretty simple and just involves counting individual blocks. However, it helped students quickly make an important realization. Without an organized system, counting one by one becomes very inconvenient, and it becomes difficult to keep track of values.

Part 1: Count blocks.

Part 2: Complete the statement with your instructor.
The more blocks you have, the harder it is to count them one by one.

Lesson 2

Part 1: Follow along with your instructor to complete this lesson.

How many blocks are in Box A? 42. How many blocks are in Box B? 42.
Even though Box A and Box B have the same number of blocks, which box was easier to count? Box A. Box A is easier to count because some of the blocks are in groups of 10 instead of all of the blocks being in groups of 1. In Box A, you can tell how many blocks you have at a glance.

Part 2: Make groups of ten in order to make the blocks easier to count. Hint: Count off groups of ten from top to bottom, starting on the left.

Lesson 3

We help students understand why we need place value by taking a look at three digit numbers.

Part 1: Follow along with your instructor to show whether or not Box A and Box B have the same value.

Part 2: Expand each number vertically. Then, show each value visually using a simple schematic drawing of the base-ten blocks. Use the following: • Square = 100; • Vertical line = 10; Dot (not too small) = 1.
