How does this quiz work?
Read each question, choose one answer among A, B, C and D, then check it: a short explanation appears after every answer. Your score out of 10 is shown at the end, and you can restart the quiz as often as you like.
What should you review before the quiz?
Reread the key facts of the lesson and the worked example. If a question is hard, go back to the matching part of the lesson, then try the quiz again. Write your work on scrap paper: most mistakes come from skipping a step, not from the idea itself.
Remember:
Subtract ones from ones and tens from tens.
If there are not enough ones, trade 1 ten for 10 ones (regroup).
Regrouping does not change the value: 52 is the same as 4 tens and 12 ones.
You can count up on a number line to find the difference.
Check a subtraction by adding the answer to the number you subtracted.
