# Grade 4 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.

• adding, subtracting, multiplying, and dividing multi-digit numbers in many ways

• comparing, adding, and subtracting fractions

• solving story problems with multiple steps and multiple operations

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: Screen Time

Ricor and Sofia have limited screen time outside of schoolwork. They are each allowed to have 1 hour for games and videos. Ricor was on his tablet from 9:45 until 10:27, and Sofia was on her tablet from 9:35 until 10:07.

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

2. What do you notice? What do you wonder?

### How could you get started?

1. Think about what you know about the start and end time for each child. Sketch clocks that show these times.

2. What kinds of calculations could you make?

3. How could you use addition and subtraction to answer some questions?

### Challenge

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

### Follow-Up

Think of something you have a time limit or a time goal for each day. This doesn’t have to be screen time. It could be reading or exercise. Record your start and end times and write a problem for someone else to solve.
