Learner’s Book 1: Unit 1, pp. 24–25
GoalSay what you see in a sentence, such as ‘there are more … than …’, and tell how many more or how many fewer.
New words
more than · a bigger number than another setfewer than · a smaller number than another sethow many more · the number of objects left over after matching
Explanation
We can say what we see in a sentence. First count each set. There are 5 birds. There are 8 bugs. There are more bugs than birds. So there are fewer birds than bugs. We can also say 5 is less than 8. To find how many more, match the sets and count the objects left over. 3 bugs have no bird, so there are 3 more bugs.
Worked examples
There are 4 fish and 6 chicks. There are more chicks than fish. Match them: 2 chicks have no fish. There are 2 more chicks.
There are 6 flowers and 3 carrots. There are fewer carrots than flowers. We can say: 3 is less than 6.
Lola has 9 apples. Kenji has 6 apples. After matching, 3 of Lola’s apples have no partner. Kenji has 3 fewer apples.
Class activity
Sentence game: take two small piles of things, for example 5 buttons and 8 stones. Count each pile and say: ‘There are … buttons. There are … stones. There are more … than …’. Then match them to find how many more.
