# 1st Grade Halloween Math Game

Have a great treat by playing this 1st Grade Halloween Math Game as you add numbers within 20. Practice your math skills and have fun destroying different spooky monsters. For each correct answer to a math problem, you will enter a half a minute bonus round.

Remember, you can add zero to a number, or a number to zero and the result wil be that number. Also, number sentences can be arranged horizontally or vertically and still end up with the same sum. For each bonus round, you will have 30 seconds to smash and destroy different monsters by clicking on them. Watch out for a few fast moving monsters, as they are not too easy to catch. The game can be played on computers, smart boards, iPads, and other tablets. You do not need to install an app to play this game on the iPad.

The game is aligned to these standard:

CCSS.1.OA.6
Add and subtract within 20, demonstrating fluency for addition and
subtraction within 10. Use strategies such as counting on; making ten
(e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to
a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between
addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8
= 4); and creating equivalent but easier or known sums (e.g., adding 6 +
7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
