Sample questions

A few real prompts from the game to help you choose an activity for your class.

01
Sort the kinds of data into groups.
Sort into
- counted
- measured
- the number of students
- height
- the number of books
- weight
Read the explanation
Data you count and data you measure are collected in different ways.
02
Sort the numbers into groups.
Sort into
- divides exactly by 3
- does not divide exactly by 3
- 15
- 16
- 24
- 25
Read the explanation
A number divides by three exactly when the sum of its digits does.
03
Sort the sums into groups.
Sort into
- needs multiplying
- needs dividing
- 6 bags of 4 - how many altogether?
- 24 shared between 6 bags - how many in each?
- 5 boxes of 9
- 45 shared between 5 boxes
Read the explanation
Which need multiplying and which need dividing - the question tells you.

Game teaching guide

What children will practise

Tell data you count from data you measure, a first step before collecting data for a pictogram (indicator ค 3.1 ป.3/1), with review of dividing by 3, choosing multiply or divide, and units of capacity versus weight.

What's in the worksheet

4 sorting questions with 2 boxes each - The number of students and the number of books are counted; height and weight are measured - 15 and 24 divide exactly by 3; 16 and 25 do not - "6 bags of 4, how many altogether?" needs multiplying; "24 shared between 6 bags, how many in each?" needs dividing - Litre and millilitre measure liquid; kilogram and gram measure weight

How to use it in class

This set has no pictogram to read, so it suits the lesson before collecting real data, about 6 minutes, team mode. - After Q1, collect some countable data as a class, such as favourite fruits, and draw a pictogram on the board - For dividing by 3, let pupils chant the 3 times table to check - Play it linked to the class to record results in the mark book

Common sticking points

- Putting weight and height under "counted" because they also give numbers. Ask "Did we get it by counting one by one, or with a measuring tool?" - Putting 25 under "divides by 3" because it is a familiar 5-times number - "24 shared between 6 bags" and "6 bags of 4" use the same numbers, so they are easily swapped. Check whether the question asks for the total or the amount per bag
