Counting on in 10's from any number


We are great at counting forwards and back in 10s from 0. e.g. 10, 20, 30, 40, 50, 60, 70, 80, 90, 100. 


Today we started thinking how we count on in tens from other numbers. 


We used Numicon to help us to see the pattern.


Start on the number                                                     







Count on ten makes 11



Count on ten more makes 21



We found out that ony the tens number changes because we are adding ten each time. 

Can you guess what will come next?



Tally Marks

We found out that you can show a number in all kinds of ways. Tally marks are one way.




                  This is how to do it.




Today our first superhero mission was to learn how to record our house points using these special marks.




We use tallies to collect data or information. What do you think they were collecting information about below?


What did they want to find out?
