The fourth graders all made math games to play at math night. They worked on them for a very long time. Parents, students, siblings, Debra (the math teacher),  Dan, Tara, and Deborah (the fourth grade teacher) were at family math night. Debra the Lower School Math Teacher has helped arrange the math night, like she has done many years in the past. Multiplication, Division, addition, subtraction, and fractions were incorporated into the math games. While making the math games we improved on our math facts.

A few days after math night we played each others games in our classrooms. We played games that we didn’t get the chance to play at math night. We went around and and played each others games. I was surprised that there were so many different ideas and not one was alike any other. The math games were educational as well as fun! Some math games were harder than others.

Some made board games others made ball games and some made card games. Some math games were, Math Bowling, Multiplication Chutes and Ladders, Math skeeball, and more! The fourth graders had two months to make the math game. I think the math games are a very important part of the 4th grade year.

In fourth grade we have been doing multiplication and division. We use arrays to help us while doing our work. We show our work on the board.  Problems like 6 x 5 are easy and fun. We have studied our combinations up through 12 x 12. When we get a harder problem we are learning new ways to solve them.

In the picture below, Tara wrote down my work in red. I didn’t know this by heart at the time so I did 13 x 4 which is 52 and then I did 52 x 2 which is 104. I knew I needed to double 52 to get to 104 because 4 is half 8.

Recently, I have been working on showing my math using Show Me on my class iPad. It’s an app where you can draw and explain what you are doing and it will record your voice. The first time I did it was for a math problem 17×6. I made an array and split it up into 10 and 7. Then I did 6×7 and 10×6 and I put them together. In the end the answer was 102. You can use different colors like black, grey, red, blue, green and orange. You can also erase things and add typing and use a picker and draw on it. Show Me is really fun and I really like to use it.
