Which of these calculations do you see as most alike? Why?
-3.4 + 5.7 = 1.7 3/5 + 2/3 = 1 4/15 3 ½ + (-4/3) = 2 1/6
What did Tom Write?
Tom wrote down two positive integers consisting of the following digits:
1, 2, 3, ,4 ,5, 6. Each of the digits appeared in only one of the two
numbers and only once. When tom adde4d up these numbers he
obtained 750. What positive integers did Tom write?
For lower students: demonstrate on a number line and using algetiles
that adding opposite integers always = 0
For other students: You are using an elevator in your hotel, you go up 8
floors (ground floor is the first floor), the door doesn’t open and you
need to go down two floors. Use a number line to demonstrate where
you end up.
