Use this Common Core resource to help students visualize percentages of whole numbers. Break whole numbers into 10 equal parts that represent 10% of the given whole. This will require them to divide by 10 then use multiplication or repeated addition with decimals to compose the whole (see example). Then students can estimate their answers. Students then have the opportunity to multiply the percent by the given whole number to check their estimation. We did this with two sixth grade classes this week and the students loved it and felt confidence in this standard. Enjoy!
