This is a 15-page document (plus a few pages of answer key) that is intended for an introduction to decimals. It includes tenths and hundredths with practice on number lines, word form, comparing, and adding and subtraction. The emphasis is on making sense of the numbers and the place value. All computation problems are presented horizontally, and many can be solved mentally with adequate understanding of tenths and how they combine to form wholes. I created this for use with on grade level and above grade level fifth graders who are beginning their study of decimals. The worksheets are designed for use as classwork or homework.
