# 100 Number Grid Fireworks

**100 Number Grid Fireworks** – This educational activity helps kids to develop an understanding of patterns and number relationships by utilizing a number grid. Each horizontal row represents a tens digit. As you move from top to bottom, the tens digit increases by one and the ones digit remains unchanged. The vertical rows represent the ones digits. As you move from left to right, the ones digit increases by one and the tens digit remains unchanged.

Children must help the monkey find the fireworks. The monkey will tell you a number that represents where the firework is hidden in the number grid. The more fireworks you find, the more you will get to launch during the celebration!
