Multiply a Fraction times a Whole Number
Mariana uses snap cubes to find 3/7 of 14. To do this, she counts out 14 cubes and makes 7 equal groups. Then she combines 3 of these equal groups to find that 6 is 3/7 of 14. She can see
2 + 2 + 2 or 3 groups of 2 to determine this.
Maribel also shows how she constructed the same. This makes it visual and concrete for my bilingual students to see that 3/7 of 14 is 6, and 4/7 of 14 is 8.
The children really enjoy this activity because it made sense to them!
Rigoberto shows 3 of 4 equal groups of 12. His answer is 3 + 3 + 3 or 3 groups of 3. Therefore, he can see that 3/4 of 12 equals 9.
Mariana records her work on her paper. She proves her answers by drawing pictures of the blocks and circling the number of groups to show her solution.
5/6 of 12 = 10, because she counts out 12 cubes and makes 6 equal groups with them. Then she circles 5 of the 6 equal groups.
Esmeralda knows that n/n = 1, so common factors can be factored out in each problem to simplify the answer.
Jessi constructs 2/9 of 18 to prove that his answer is 4. Again, he counts out 18 cubes, divides them into 9 equal groups, and takes 2 of those groups to find the answer of 4 cubes.
The children made a lot of connections today! :)
