Young counters will enjoy this beginning addition activity; they get to color as they go! For each set of 10 fish they color some green and leave some white. Then, they fill in the blanks to create an addition sentence with the sum of 10. There are six of these sets (encourage kids color a different number of fish for each). Next, they complete 10 number sentences (again with 10 as the sum for each) and write in missing addends. They might catch onto a pattern here: the addends increase by one each time.
