I like Singapore Math because it teaches concepts but I also like Kumon for mastery and rote teaching. Mixing both ideas worked well for my kids.
Sharing some of my math manipulatives to you which you can easily do as well.
We learned addition with this. This has greatly helped my 5 year old math-challenged kid to understand the basic concepts of addition.
We call this our Addition Machine. Pompom balls are placed on each cup and it will sum up as it falls in the basket.
I also introduced number bonds thru our number links. I have a 5, 10 and 20 links for my kids level.
The pipe cleaners and beads are placed on each link. They will come up with different addends to come up with that number.
This gave my Kindergarteners a quick idea of the concept. Now, they are much faster and I can soon introduce worksheets once they can fully grasp the idea.
Manipulatives can be just everyday household materials. But, if you want to buy your own, you can buy them at Hobbes & Landes, Toys R Us, Toy Kingdom, National Bookstore or Office Warehouse.
Pipe cleaners, pompom balls can be bought at Office Warehouse, Little Town Bookstore, or at Daiso.
Happy Math day!
