## BLOG ARCHIVES - Fractions & Decimals ### Decimals Using Base 10 Blocks and Money

Last week, I shared an activity that you can use when introducing fractions with denominators 10 & 100. Click here to read that blog post. It includes a freebie for your guided math groups! Today’s blog post includes a math mat that will helps students represent decimals in various ways. In fourth grade, students are ### Adding Fractions with Denominators 10 and 100

In third grade, students focused on fractions with denominators 2, 3, 4, 6, and 8. In fourth grade, students are introduced to fractions with denominators 10 and 100.
