Here is a great way to practice comparing fractions with unlike denominators using the least (or lowest) common multiple method. Cuisenaire Rods help make it visually obvious what we are talking about.
Be aware, though, that this is not an activity for those who have just recently been introduced to Cuisenaire Rods or fractions. This should be done after much play/work with both first so that children understand what the rods stand for.
This free math video shows a great way to practice comparing fractions with unlike denominators using the least (or lowest) common multiple method. Cuisenaire Rods help make it visually obvious what we are talking about.
Be aware, though, that this is not an activity for those who have just recently been introduced to Cuisenaire Rods or fractions. This should be done after much play/work with both first so that children understand what the rods stand for.
The game idea in this free math tutoring video comes from LetsPlayMath.net. We just added Cuisenaire Rods to make it more tactile and visual. If you watch through the whole thing you will see my girls using the distributive property over and over to figure out multiplication facts. And at the end, you’ll see what kind of number awareness happens when kids have a chance to work with these rods a lot. They understand this stuff better than I do, I can promise you that!
