Grade 4 Math: Multiplication: Two Digit

Two Digit Multiplication: No Regrouping – with Place Value Table

Students have already learned to multiply one-digit numbers by one-digit numbers. In this lesson, students extend their knowledge to multiply when one of the numbers is a two-digit number and one is a one-digit number.

The concepts are illustrated using a Place Value table along with the multiplication problem in the standard algorithm format.

Two Digit Multiplication: No Regrouping – All Steps

In this lesson, students multiply 2-digit numbers by 1-digit numbers that do not require regrouping without the Place Value Table used in the prior lesson. Students use the standard algorithm to solve the problems, but each digit in the answer is evaluated separately and feedback is given for each digit.

Two Digit Multiplication: No Regrouping – Answer Only

In this lesson, students multiply 2-digit numbers by 1-digit numbers that do not require regrouping without the Place Value Table used in the prior lesson. Students use the standard algorithm to solve the problems. Only the final answer is evaluated.

Two Digit Multiplication: Regrouping – with Place Value Table

In the three prior lessons, students have already learned to multiply one-digit numbers by one-digit numbers using the standard algorithm when regrouping is not required. In this lesson, students extend their knowledge to multiply 2-digit numbers by 1-digit numbers when regrouping is required.

The concepts are illustrated using a Place Value table along with the multiplication problem in the standard algorithm format.

When the product in the ones place is greater than 10, students learn to make a ten in the tens place.

In this lesson, students multiply 2-digit numbers by 1-digit numbers that require regrouping without the Place Value Table used in the prior lesson. Students use the standard algorithm to solve the problems, but each digit in the answer is evaluated separately and feedback is given for each digit.
