We’ve been using the fraction chart and a pencil a lot to look at equivalent fractions. I have the kids line up the pencil on 1/2 and then ask them what some equivalent fractions are. We also have spent a lot of time building equivalent fractions with our manipulatives. Again the fraction table pictured below is from Right Start math (a math curriculum that uses Montessori concepts and hands-on math manipulatives and games), but you can print out something similar here.
Another game that was really terrific was building fraction to make one. So for example, we had the cards 1/2 and 1/2, 1/3 and 2/3, 1/4 and 3/4, 1/8 and 7/8, etc. We mixed up all the cards and then played a memory game. If DD turned over a 4/5 card, then she had to find the 1/5 card to make a match.
I found this cute fractions game (pictured below) at pbskids and had the kids play a number of rounds. Each round got progressively harder until the kids had to create equivalent fractions such as 14/17=7/8 LD was able to figure those out, but that level was too difficult for DD (she is 6) at this point.
I made up a few worksheets to go with the fraction table we’ve been working with. I don’t expect the kids to do this on their own at this point, instead they use the table to figure out the answer. You can download the fraction worksheets I made here.
