Add and take away · Lesson 13 of 32

Put together: add

Read with an adult. Take your time. You can say, point, draw or write your answer.

Let's look together

Adding joins groups. The + sign means add. The = sign means both sides have the same value.

We can build a number sentence with blocks. Count both groups together to find the total.

3 + 2 = 5
Look, point and talk with your adult.

Watch how I do it

I have three blocks and get two more. I count 1, 2, 3, 4, 5. I write 3 + 2 = 5. Five is the total.

Your turn

You have four blocks and get three more. What is 4 + 3?

Have a go before opening the answer.

Let's check together

7. Four and three make seven.

Try it away from the page

Make two groups of your choice with a total below ten. Draw them and write an addition sentence.

Open your writing and drawing pad

Write, draw or show your working. Use a mouse, pen or finger. This pad is not a submitted answer.

Not saved to your account. Download your drawing as PNG and your typed notes as TXT before leaving or refreshing. They are separate files. Do not enter private information.

Open a picture saved on this device to draw on it again. Opening replaces the drawing, but Undo can restore it. PNG only, up to 4 MB and 4096 × 4096 pixels. The picture stays in this browser; it is not uploaded. Paper lines in a saved picture become part of that picture.

Drawing is unavailable. Use the typed working area below.

Your pad is empty.

Open a UTF-8 TXT file from this device, up to 40 KB and 10,000 characters. It stays in this browser. Opening can be undone until you type again. Downloads keep a new copy; they do not change the file you opened.

Typed notes are not submitted answers.

Explore and practise freely. Opening this lesson or using the writing pad does not save completion or a score.

Adult notes · prerequisites, safety and coverage

Prerequisite: parts and whole. Read equals as 'has the same value as', not 'write the answer now'. Also show 5 = 3 + 2.

Use large counters, blocks and paper before symbols. Revisit a lesson until the child can show and explain the idea. Numbers grow from 0–10 to 20, then 100; these pages are not a one-sitting course.

These are teaching introductions, not a claim of mastery. Open the subject's coverage map and limits.
