Class 3 Maths Chapter 12 Revision Notes: Give and Take

Chapter type: Arithmetic — consolidating addition/subtraction, with an introduction to estimation.

Key ideas to remember:

Giving (subtraction) xe2x80x94 when something is given away or removed, the total decreases — solved using subtraction.

Taking/receiving (addition) xe2x80x94 when something is received or added, the total increases — solved using addition.

Estimation xe2x80x94 rounding numbers to the nearest ten or hundred to quickly find an approximate answer.

Checking reasonableness xe2x80x94 comparing an exact calculated answer to an estimate to see if it makes sense.

What you should be able to do after this chapter:

1. Solve give-and-take word problems using addition and subtraction correctly.
2. Round numbers to the nearest ten or hundred to make a quick estimate.
3. Use an estimate to check whether an exact calculated answer is reasonable.

Remember: A quick habit worth building for life: before trusting a calculated answer, round the numbers and estimate — if the exact answer and the estimate are very far apart, something likely went wrong.

Frequently Asked Questions

Do I round up or down when estimating?
Round to the nearest ten or hundred — if the next digit is 5 or more, round up; if it is less than 5, round down.
