Word problem
Cathy has 6 pair of black gloves and 6 pair of blue gloves in a drawer. She needs to pick out a matching pair of gloves in complete darkness. How many gloves does she need to pull in order to make sure she gets a match (one left hand glove, one right hand glove of the same color)?
Logic
Three friends and a missing cookie. Based on the friends responses, who stole the cookie?
2-variable constraints
In the land of gnomes and dwarfs, there are seven total that came to a party. Using that the dwarfs ate three more cookies than the gnomes, each being ate one cookie, and some graph paper, how many dwarfs and gnomes were at the party.

Warm up
4 + e = 10 what is e?
9 - f = 3 what is f?
10 - g = 2 what is g?
1 + 8 = x
x - 5 = y
x + y = z
what is z?
i + 5 = 10
j + j = 14
j - i = k
what is k?
Number sorting
Sort the numbers in ascending order
8 2 10 15 13 4
18 5 22 11 9 40
d a j x s k
Sort the numbers in descending order
9 1 3 11 5 8
Sphero
Let's make a path around the classroom and see if we can program the sphero to navigate the path. The kids picked a route and programmed the sphero to navigate the classroom.
