Lesson details
Key learning points
- A pictogram is a graph that uses pictures to represent information.
- A pictogram’s key tells us what each picture represents.
- Whole − part = difference
- We can calculate the difference by counting on from the known part to the whole.
Keywords
Pictogram - A way of showing data using images.
Difference - The result of subtracting one number from another. Way in which two or more things we are comparing are not the same.
Counting on - A mental strategy used to add numbers.
Subtraction - To partition one part from another (the subtrahend from the difference), or to decrease an amount by taking an amount away.
Common misconception
When comparing the larger to the smaller number and then the smaller to the larger number, children may record this as 15 - 8 = ? and 8 - 15 = ?
When finding the difference, we can compare the larger to the smaller number and the smaller to the larger number. Stress that each time, we record this in the same way as subtraction isn't commutative (whole - part = part).
