Learning Objectives

Students will understand place values of two and three-digit numbers and be able to write the expanded form of given numbers.

Introduction

(10 minutes)
  • Remind students of what they have already learned about place value. This should include how 2-digit numbers have a ones and a tens place.
  • On the board draw a place value chart, and in it write a two-digit number.
  • Using base ten blocks, show your students this number.
  • Use craft sticks to count the students in the class. For example, If you have 24 students you should also have 24 craft sticks.
  • Count out groups of 10 sticks, wrapping each group with a rubber band.
  • Have your students count the number of groups. Remind them that there are ten sticks in each of those groups, so even if they counted two groups, that means there are 20 sticks total.
  • Use ten frames to represent the same number.
  • Using linking cubes to represent this same number again.
