David put these jelly beans into ten frames. How many jelly beans are there?
The question tells us, and we can see from the picture, that David has put his jelly beans into ten frames. And he started to count them. 10, 20, 30, 31, and so on, and so on, and so on. We can see that David has 30 jelly beans in his three ten frames. Three tens make 30. 10, 20, 30.
David also has some jelly beans left over which he didn’t put in a ten frame. Let’s count how many jelly beans there are left over. One, two, three, four. What is 30 and four more? Let’s start at 30 on our number line and count forward four more. 31, 32, 33, 34. Three tens and four more makes 34. David has 34 jelly beans altogether. 30 and four more equals 34.
