I did a blog yesterday about a maths integration activity for my grade 1 PE classes. A modified version of this game that I used for my kindergarten classes worked well, so I will describe the activity.
Game # 1 (warm up)
The same as warm up game for grade 1. Each team has their own set of ten colored dots. The dots are spread out all over the gym (face down). On 'Go' command, the students must run out, find their team dots, bring them back to their team area and place them on the floor in order(numbers 1-10). The game can be repeated with them creating new formations (square, triangle, zig zag) provided the numbers are in order.
The modified version of the grade 1 game is that they find numbers that add together to form a correct sum. However, it becomes a bit too complex for them to go out and trade numbers with other teams. If there is a super clever maths student, you can suggest to them to go to other teams to find a number they may need. Essentially, the game is very similar to the grade 1 maths activity as described in yesterday's blog. Try it out!
