Give your 1st grade students focused base 10 practice with Using Base 10 Blocks to Write Numbers Worksheet, a print-ready PDF with an answer key included. It is built for busy weeks: print a class set, hand it out and students know exactly what to do.

What students do

The page asks students to: “Write the number that each set of blocks represents.” The items build steadily, which helps children move from guided to independent practice in a single sitting.
