# Grade 3 Math at Home

Welcome! We’ll update this page every weekday with a new math activity. Many of the activities will be fun and worthwhile for students of all ages so that you can do them as a family. The following day, we’ll share examples of how other people did the activity so you can check your work and stretch your thinking.

The resources on this page focus on the major work for third grade:

• multiplication and division to 10 ✕ 10, and multi-digit addition and subtraction

• understanding fractions

• solving problems about area

We’ll do a lot of work with measurement and geometry, too!

## Math & Game Tools

DIY spinners, origami dice, and more!

## Math in Our World: Gaming Map

I’m playing a lot of board games lately. I like this game because I get to make a map of a town.

I have to work around the mountains and the canyon in the center. I can draw forests, villages, farms, or water.

Every section I draw has to be a rectangle with at least four grid squares inside. Monsters will live in any spaces left over.

My score is the sum of the areas of the sections I draw. The monster villages don’t count. I earn bonus points for larger sections.

1. What do you notice? What do you wonder?

2. Show what is happening using pictures, models, or numbers.

### How could you get started?

1. What is the largest rectangle you could draw? Will that cause a spot that could be taken over by monsters?

2. What sections of the map might be the hardest to cover? You could start there to avoid leaving spaces for monsters.

### Challenge

1. Show your work to someone else, and explain your thinking. Did they understand?

2. Ask whether they have any other questions you can answer!

### Follow-Up

Make your own rules for this game. Maybe the map can include L-shaped or T-shaped sections.
