Build a city or just do your math with these blocks or do a little of both.The Fraction Building blocks have tall sky scrapers and small little buildings, all with windows that are multiples of each other.
The tallest sky scraper has 12 windows while the next in size is half of it i.e; 6 windows. So you can add 3 more blocks with 2 windows to make it as tall. Or would you rather add one with 4 windows and one with 2? Do 2 blocks with 6 windows each add up to the tallest of towers? You can build a city with other props like trees, roads etc, even as you learn fractions.16 multi-colored beech wood blocks with upto 12 windows on them.
The windows make it easy to add and subtract and master fractions. The colors give visual clues. A child learns the concept of 1/2, 1/4, 1/3 and 1/6 using these colorful wooden blocks. Add more sets for more complexity and older children.
