## Lesson: Place Value to 1,000

Introducing the Concept

Before beginning place value to 1,000, review place value through 99. If the children spend some time reviewing, the transfer of knowledge to 1,000 will be much easier. Take time to practice many groupings of two-digit numbers, using the language of place value.

**Materials:**84 connecting cubes, tens and ones mat for each child or pair of children

**Preparation:**Give a tens and ones mat to each child. Prepare a chart of number words. One column should include the number words one to nine, a second column ten to ninety by tens, and a third column, eleven to nineteen. Place it so children can refer to it.

**Prerequisite Skills and Concepts:**Children should know how to count to 100. They should be familiar with number words and what they look like when written.

Give each child (or pair of children) 26 cubes.
