Lesson Plan: Subtracting Two-Digit Numbers on Number Lines Mathematics • Second Year of Primary School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to count backward on number lines to subtract two-digit numbers.
Objectives
Students will be able to
- count backward along a number line to subtract a pair of two-digit numbers,
- use partitioning to help subtract across a 10,
- apply knowledge of subtracting using a number line when solving word problems.
Prerequisites
Students should already be familiar with
- subtracting single digits from two-digit numbers by counting backward on number lines,
- partitioning to help with calculations.
Exclusions
Students will not cover
- subtracting two-digit numbers without using a number line,
- subtracting from three-digit numbers.
