Tally Marks

This week we have been reviewing how to use tally marks when recording and counting information quickly. First we read the book Tally Cat Keeps Track by Trudy Harris. We then talked about why it is more effective to count using tally marks.

We agreed that is alot quicker to count by fives or tens and then add the extra numbers, than it is to count by ones. Isabelle also bought to our attention that it is neater and less confusing when it is time to count the collection of marks. We all had a try at quick fire tallies, in which I  wrote a number on the board and the students had to represent that number using tally marks.
