In a tally chart each thing has a row of tally marks.
The fifth mark goes across each group of four.
That way you can count quickly in steps of five.
The filled-in example below shows the answer.
Example
For parents
What does this exercise practice?
The tally chart introduces bundled counting in fives and prepares for bundling in tens.
Common pitfalls
Children often count the marks one by one. The bundles of five allow faster counting: five, ten, then on by ones.
How to practice at home
While playing, count how often something happens and make a mark each time it does.
