Introduction to Decimals - Represent Decimals in Different Ways

This interactive introduction to decimals activity reinforces that there are different ways to represent decimals. Students SHOW a decimal on a number line, with place value blocks, in word form, or as a fraction/mixed number. You can easily differentiate learning for students by varying the place value used on the decimal cards. In some cases, there is no one right answer so it allows for multiple entry points for learning.
