I am doing a little coding with the students during conference week. 3rd-5th graders are using the website www.code.org . K-2 is using an app called Coding for Kids. Many of the students really enjoyed it so I am sure they would like to practice some more at home.
We are using the Singapore Bar Model Drawing model for problem solving in Math Lab. There is an interactive activity on Math Playground (and an app version) called Thinking Blocks. If your child could spend some time on this interactive activity at home, it would help them with problem solving and what we are doing in the lab. They will have some time in Computer Lab one day soon to work on this website too.
