Ask a five-year-old what comes after 79 and you may hear « seventy-ten. » The jump to a new ten is where counting stumbles. This kindergarten hundred chart puzzle worksheet puts that jump on paper. Four colored grids each hold sixteen squares. However, only the colored squares show a number, so the white ones need filling. Children read across each row and fill in the gaps, from single digits up into the eighties. The PDF has two pages: the worksheet and its answer key.
