Lesson Plan: Multiplying a Two-Digit Number by a One-Digit Number: Column Method with Regrouping Mathematics • Fourth Year of Primary School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to use the column method to multiply a two-digit number by a one-digit number for calculations where there is regrouping.
Objectives
Students will be able to
- use the column method to multiply a two-digit number by a one-digit number when regrouping is required,
- correctly record the regrouping of 10 ones into a ten,
- model the calculation and describe how each step is represented in the written solution,
- find missing numbers in partially complete solutions,
- identify errors in solutions.
Prerequisites
Students should already be familiar with
- the multiplication tables up to ,
- using the column method to multiply without regrouping.
Exclusions
Students will not cover
- mental multiplication strategies.
