13 is 10 ones and three leftover.
we can see that the 13 sticks have been grouped together into a bundle of 10, and
there are three leftover. 10 ones and three more ones makes
13. Which of the following shows
17?
All of the pictures have one ten
bundle. So we know that each of the numbers
is greater than 10. Remember, we’re looking for the
number 17. So we know that each of the
pictures shows one ten and some ones leftover. How many ones are leftover in the
first picture? Let’s count them. One, two, three, four, five, six,
seven, eight. So the first picture has 10 ones
and eight left over. This makes the number 18. The second picture has 10 ones and
some ones left over. Let’s count the number of ones
leftover. One, two, three, four, five, six,
seven. One ten and seven ones makes
17. So this is the picture that shows
17. Let’s check how many ones are
leftover in the final picture. One, two, three, four, five,
six. One ten and six ones makes 16. So the picture in the middle shows
17, one ten and seven ones.
