Basic Facts Boxes 2021

I completed basic facts boxes addtion. The basic facts boxes challenge is to answer the questions quickly.

I got 100/100 correct and my time was 6m and 43s. The hardest row of addtion to do was my 5 and 4 addition.

I need to work on my 5 and 4 addition because I kept on getting stuck on them, and moving on. My goal is next time to do addition and keep on moving on.
