This video explains arrays and the expanded algorithm for 2-digit × 2-digit multiplication problems in more detail.

Dec 4, 2020 · Short tutorial on how to multiply double digit times double digit problems using the expanded algorithm.

Apr 11, 2024 · Do you need to simplify multi-digit multiplication for your students and make it easier to understand? Students can use the expanded form to break down large numbers into their place values and multiply more efficiently. This is called the Expanded Multiplication Method.

Fluently add and subtract multi-digit whole numbers using the standard algorithm. Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations.

Multiply up to two two-digit numbers with place value understanding using area models, partial products, and the properties of operations. Use models to make connections and develop the algorithm.

Apr 19, 2021 · Here we will solve some examples of multiplication of 2 digit numbers and 3 digit numbers by 1 digit numbers. Example 1: Multiply 62, 5? Solution: 1. Write the expanded form of a number and then multiply by 5. (60+2)*5. 2. Multiply 5 with 2 and 5 with 60 and then add the products. 60*5+2*5. =300+10. =310. Multiplication of 62,5 is 310. Example 2:

These task cards ask students to: -Use array models and expanded algorithm to solve 2-digit by 2-digit multiplication problems. -Analyze sample student solution for errors and explain errors. -Solve multiplication word problems. There is a blank recording sheet provided for your students to record their answers.

Begin by thinking of the expanded notation for the numbers being multiplied: 66 = 60 + 6 49 = 40 + 9 ight or the left. Starting on the left can help students stay on track and find Figure out what parts of the numbers need to be multiplied together.

This worksheet models an example of double-digit times double-digit multiplication using partial products and expanded algorithm. Then there are three other equations to be completed as practice problems.
