Remind students that a fraction is composed of a numerator and a denominator. Show a problem and tell students that
of the cars are red. To determine how many cars there are in total, you have to compose the whole fraction. Show that you multiply by 8 to get
. Emphasize that the quantity of red cars (4) also must be multiplied by 8. There are 32 cars in total. Together with the students, go through these steps with the problems using the cake and strawberries. Use the next problems to check that students are able to determine the total by using a fraction when using a fraction bar. Finally explain fraction story problems to the students. Make sure that students follow the steps of solving a story problem, and that they select the correct numbers from the story problem.
Check that students are able to find the whole given the part and the fraction by asking the following question:
- Which steps do you take to determine the total when you have a fraction?
