Lesson Plan: Subtracting Hundreds from Three-Digit Numbers Mathematics • Second Year of Primary School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to subtract multiples of one hundred from three-digit numbers and model this using place value equipment, number lines, and part–whole models.
Objectives
Students will be able to
- represent subtracting a multiple of one hundred from three-digit numbers using place value equipment,
- use place value language to describe subtracting a multiple of one hundred from a three-digit number,
- represent subtracting a multiple of one hundred from a three-digit number on a number line,
- complete part–whole models to find the result of subtracting multiples of one hundred from three-digit numbers,
- subtract a multiple of hundred from a three-digit number without using a model,
- determine what multiple of one hundred has been subtracted from a three-digit number.
Prerequisites
Students should already be familiar with
- subtracting ones from three-digit numbers,
- subtracting tens from three-digit numbers.
Exclusions
