This post contains 30+ basic counting and math sheets for late kindergarten and first grade. The practice sheets are presented using tally-type graphics and the box model, so it’ll be easier and more fun for kid to learn.
If your kid is just starting out with numbers, I’d also recommend these Number Writing Practice Sheets for them. On the other hand, if your kid has already mastered counting and writing number, I’d recommend these Addition and Subtraction Math Worksheets with different levels of difficulty from single-digit to two- or three-digit math problems.
