Broken Calculator is an activity that challenges students to find multiple ways to make a number without just writing the number. For example: my number is 20 but my 2 key is "broken" so I could write 11+9 or 30-10.
Name that Number is a game where children try to make a certain number using the five cards in front of them. If I have a 5,1,10,7,and 9 in front of me and I draw a 6, I can make a 6 three ways. I can use 7-1 or 5+1 which uses up 2 of my cards. I can also use 10-5+1 which equals 6 and uses up 3 of my cards. This is a great game where kids can differentiate according to their ability.
Balloon Double is a game where kids practice their double facts such as 4+4 or 10+10. The student rolls a die or two (depending on which gameboard they chose) and they double that number. Once they have doubled the number, they place a chip on that number on their gameboard. When every balloon on their gameboard is covered, they have won!
Compliments of Ten Memory is a great way to learn the compliments of ten. If you flip over 2 cards and they add up to 10, then you get to keep the match! The compliments of ten are 0+10. 1+9, 2+8, 3+7, 4+6, and 5+5. The more practice the students have, the less they will need to use their fingers!
Here is a group working on the minus 9 lesson from today! We are cramped, but we have fun!
Here is a student working on math boxes at his seat. All of the math boxes review skills that we have already learned. Today we reviewed counting dollars and coins, telling time, writing a fact family, drawing a trapezoid and circling the 3 sides that are the same size, reading a graph, and writing 3 different names for the number 26 (just like the Broken Calculator game)!
