Counting the sets
Learner’s Book 1: Unit 7, pp. 99–100
GoalCount how many are in each set and say which set has more or fewer.
New words
more · a bigger numberfewer · a smaller number of thingsaltogether · all the sets counted together
Explanation
After we sort, we count each set. Write down how many are in each one. Then we can compare the sets. The set with the bigger number has more. The set with the smaller number has fewer. If both sets have the same number, they are equal. To find how many there are altogether, put the sets back together and count them all.
Worked examples
Look at the picture: there are 6 fish and 4 birds. 6 is more than 4, so there are more fish than birds. There are fewer birds than fish.
3 apples and 4 carrots. 3 is fewer than 4. Altogether: 3 and 4 make 7 things.
Tom has 5 stars and Lola has 5 stars. Neither set has more. The sets are equal.
Class activity
Sets in a bowl: pour a mix of two kinds of small things (for example beans and buttons) onto a plate. Sort them into two sets and count each one. Which set has more? Which set has fewer? How many altogether?
