Learning Resources Interlocking Gram Unit Cubes – 1,000 Pieces, Ages 6+ Math Classroom Teaching Aids

Using in my second grade math classroom
I often use this during math lessons. Really came in handy when introducing re-grouping in two digit subtraction & there are enough pieces for students to model problems as well. The pieces are very small and not particularly easy to click together or pull apart, but still does the job. Can be used for multiplication as well. For three digit concepts or more, it’s better to get a set specifically for that (with plains and cubes) I love the container, which makes storage and clean up easy as well.

Awesome buy
My toddler son is a math genius and he absolutely loves what he refers to as his number blocks! I am so happy I made this purchase! I actually thought I was getting the thicker version of these blocks but I have no complaints because my child doesn’t put small objects in his mouth so we are good.

Math and Science multitasker 😀
We use these for homeschool both for weights and measures and for arithmetic. I wanted to get connecting blocks to illustrate carrying and borrowing in addition/subtraction and liked that these could multitask :)They do not stay together very well, but since we only make rods of 10 and it’s all on table-top it works out very well. I like that there are several colors and there are plenty of each color. A great quantity for the price 🙂 I feel that since they are made to connect they should hold together a bit more and took 1 star, but for the price I’m certainly not complaining a bit! Even in class witht he balance scale, I’d like them to be more firmly held so I can make a real block of 9g–balancing 9 loose blocks against 9 loose blocks is not very “thinky” lol. If I made a 9 cube, she’s have to think! so I do, but have to be VERY gentle handling it (especially for any larger).I has a base-10 set but I found 2 problems with it for teaching my 2 children (5yo and 8yo). First, the base-10 set I has purchased had a different color for each size, so 10 yellow “ones” would turn into 1 green “tens”. That’s confusing. My kid was processing the math as “I trade all these for a new thing” not “This is the same as that”. As soon as I got these she “got it” in one lesson. I took 2 small pieces of colored paper and labeled one “ones” and the other “tens”. I put (for example) 37 same-colored-not-connected cubes onto the ones and she counted them =37. I had her start grouping up as many into sticks of 10 as she could. I emphasized this was just us organizing and sorting out cubes (and that writing digits into numbers is just a way of us communicating the way they are sorted). She put the grouped 10’s onto the tens paper. count the cubes = 37. No “trade me those for something different”–she got it. When we started, she could add and subtract 3 and 4 digit numbers, but had no idea WHAT she was doing–just that she was doing the motions correctly. Now she understands place value fully.The following lessons involved 4 papers set up like a vertical equation (a tens above a tens and a ones above a ones). I’d put (for example) 5 tens-rods on the top tens paper and 3 ones-cubes on the ones paper. Ont the second row I’d place 2 tens-rods and 8 ones-cubes. Subtract. She very quickly understood that “borrowing” was taking a tens rod and making it into 10 ones. Tangible learning. On paper this never “meant” anything to her beyond”you change the 5 to 4 and the 3 to 13″ Now she understands what she’s actually doing!

Great for kids
Kids love and they’re very durable

Cumple con el tamaño de 1cm por lado, la calidad del plástico es buena pues es resistente

As expected. Practical tool to help with understanding math principals

Es difícil entablar los bloques aun para un adulto
