Sometimes you know how many you started with and how many are left.
Step 1: Let's Learn
Read it, or press Listen and follow the words.
The bit that went away is the gap between them.
The change is the unknown
Here you know both ends and not the middle. That is a third kind of question, and it needs the same bond thinking.
Which way did it go?
If the end is smaller, something was taken away. If it is bigger, something was added. Check that before you work out how much.
Step 2: Try It Yourself
Tap and try it out.
9 take away 5 makes 4.
Step 3: Watch an Example
One step at a time.
Watch Ana Work Out What Went
Ana had 9 sweets. Now she has 4.
- Step 1
She started with 9 and has 4 left.
Step 4: Your Turn
Practice makes it stick.

1 of 2
8 − ? = 5
2 of 2
10 − ? = 6
Step 5: Quick Check
Show what you know.
Question 1 of 2
9 − ? = 6
Question 2 of 2
7 − ? = 2
What You Learned
- Sometimes the missing bit is what changed.
