## Interactive Math Lesson - Multiplying by Multiples of 10

Are your third graders ready to take their multiplication skills to the next level? Try out this interactive math activity all about multiplying by multiples of ten with your third grade class today! Multiplication problems in this online math lesson are presented in a variety of formats, including horizontal multiplication problems, vertical multiplication problems, and multiplication word problems. Your students will become comfortable multiplying factors in which one of the factors is a multiple of ten to obtain a product that ends in zero.

Your students may be given a word problem, such as "Last night Kian slept eight hours. If there are sixty minutes in one hour, how many total minutes did Kian sleep?" Students will fill in the blank with the correct answer. They may also be asked basic multiplication questions, like "50 x 4 =" or "70 x 9 =".

If your students need a little extra help solving a multiplication problem, they can click on the "Hint" button. They will be shown a relevant pictorial or verbal clue, such as "Step 1: Insert a zero into the ones place of the product." When your students answer a question incorrectly, a detailed explanation page will show them, step-by-step, how to solve the multiplication problem correctly, so they can move through the activity having learned from their mistakes.
