The purpose of this unit of sequenced lessons is to develop knowledge and understanding of the place value structure of the numbers from ten to twenty.

These teaching and learning activities support Student e-ako Place Value 1, pages 6-15 and to complement the learning activities found in Book 5, Teaching Addition, Subtraction and Place Value.

This is the fourth of a series of units developing place value concepts. This unit builds on the previous units of work:

• Knowing five
• Using five
• Making ten

The units that follow are:

• Building with tens
• Building with tens and hundreds
• Place value with whole numbers and decimals

This is a level 2 number activity from the Figure It Out series. It relates to Stage 5 of the Number Framework.
