One number for each object
Count arranged/scattered sets with one-to-one correspondence and recognize zero.

Using it in class

Read all text and choices aloud. Point to printed symbols without saying the total. Perform the specified counter/board actions; scattered sets never exceed ten. Children can point, move counters or direct a partner. Use short rounds; the game cannot observe each child’s counting.

Give everyone time to think and discuss before one pupil acts at the board. The class explains and confirms together; hints and explanations stay until you move on.

Use an up-to-date browser on a computer connected to a whiteboard or shared display. Touch, mouse and keyboard; optional audio and reduced motion. No pupil accounts or personal devices.

Choose from 5 challenges up to the full activity. Discussion determines the duration: you set the pace.

A look inside the activities

Choose and explain

Teacher: read aloud. Point once to each dot: ● ● ●. How many dots?

Explanation and discussion

There are three dots. Counting each once gives one, two, three; do not count the gaps.

Count the dots again while a partner checks each touch.

Choose and explain

Teacher: read aloud. Count all the dots in both groups: ● ● ● / ● ●. How many dots?

Explanation and discussion

There are three dots before the slash and two after it: five dots. Count each dot once across both groups.

Teacher: copy the dots as two rows on the board and count them.

Choose and explain

Teacher: read aloud. Which rule works for a row, a circle, or a scattered set?

Count only objects that are close together.
Give every object exactly one number word.
Use the same number for every object.

Explanation and discussion

Every object needs one number word in counting order. A tracking plan can change to suit the arrangement.

Choose a small set and show your own careful counting plan.
