Grade 2 · Unit 9: Chance

Likely or unlikely?

Some things are more likely than others.

Umbrellas are common in the monsoon.

Will it rain in July?

In July, rain in Bangladesh is very likely. In January, rain is unlikely. Chance words tell us how likely things are.

A chance line

A chance line goes from impossible to certain. Even chance is in the middle, like a coin toss. Likely is near certain; unlikely is near impossible.

Spinners

Red covers most of this spinner. Landing on red is likely. Landing on yellow is unlikely, but possible.

Fair or not?

A fair spinner has equal parts. Each colour has the same chance. Is a dice fair? Why?

Test it!

Predict first: red will happen more, blue might happen. Spin 20 times and tally. Compare the results with your prediction. Were you right?
