Award Information Awarded to Question Hint Choose Family Member  ## Interactive Math Game – Multiplying and Dividing Whole Numbers by 10, 100, and 1,000

Students will strengthen their basic multiplication and division skills in this fifth grade-level interactive math practice activity. Your class will practice multiplying and dividing whole numbers by 10, 100, and 1,000 in this online math game. Math questions are presented in a variety of formats, including drag-and-drop, fill-in-the-blank, and multiple choice.

If students need a little extra help solving one of the math problems in this interactive multiplication and division activity, they can click on the hint button. They will be shown a helpful clue: "To multiply a whole number by 10 – add one zero to the end of the number. To multiply a whole number by 100 – add two zeroes to the end of the number. To multiply a whole number by 1,000 – add three zeroes to the end of the number." Or alternately: "When dividing a whole number that ends in zero by: 10 – the quotient will have one less zero than the dividend; 100 – the quotient will have two less zeroes than the dividend; 1,000 – the quotient will have three less zeroes than the dividend."

When students answer a math problem incorrectly, a detailed explanation page will pop up on the screen, showing them a complete step-by-step guide for how the problem should be solved.

Other helpful features in this fifth grade math lesson, as well as all our online math activities, include: a progress-tracker that shows students how many questions they have answered so far; a score-tracker that lets them know how many problems they have solved correctly; and a read-aloud button that allows them to hear the question read to them in a clear voice. This option is a favorite among teachers with ESL/ELL students!  ## Why Choose I Know It
