CHAPTER 2: NUMERATION

Lesson 2: Representing and Renaming Numbers

Goal

Represent and rename numbers to 1000.

Instructions for Use

Base Blocks allows you to build different models of given numbers using base ten blocks.

At the bottom right, click the down arrow next to “Columns = 4” to change it to “Columns = 3.” Use base ten blocks to represent a three-digit number in different ways. Click blocks at the top of the chart so that they appear in the columns below. The number currently represented in the chart will appear to the right of the chart. You may use 100s, 10s, or 1s. To delete one of the blocks, click and drag it into the garbage bin at the bottom right of the chart. To clear the chart, click “Clear.” Then try representing the same number using a different combination of base ten blocks.
