Lesson: Multiplying a Two-Digit Number by a One-Digit Number: Column Method with Regrouping Mathematics • Fourth Year of Primary School

Join Nagwa Classes

Attend live Mathematics sessions on Nagwa Classes to learn more about this topic from an expert teacher!

In this lesson, we will learn how to use the standard algorithm to multiply a two-digit number by a one-digit number for calculations where there is regrouping.

Lesson Plan

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.
