The purpose of this week of investigations and video watching is to learn about math and math skills like how to figure out how to find the area of a square. The purpose of watching videos was to work how you want to and not be stressed when you work. The purpose of practicing problems was to see the different ways people learn. The problem that chose to extend is the squares to stairs. The squares to stairs problem is about figuring out how many squares there will be in the next set of stairs. I chose this problem because I liked it and I solved it pretty well. An approach I took to solve the problem was to add the next number of squares to the other squares or stairs. I also added the next few set of squares to the past sum. This week of work shows that I worked because I put effort and that I solved the answers correctly. I worked pretty hard on these problem and I am ready to move on.
