hand2mind Numberblocks 11-20 MathLink Cubes Activity Set, Elementary Math & Counting Toys, Ages 3+

If your baby loves number blocks then these are a PERFECT gift! My son is on the spectrum and they are his favorite! I've gotten him zero to one hundred and he loves them all.

my son absolutely loves numberblocks and loves this toy, id just suggest having a separate container for this considering it has alot of small pieces to it that are hard to get back in the box, but great toy altogether

between these cubes and the show my almost 4yr old is counting to 30, by 10s to 100, and knows addition combinations of 1-10 - highly recommend

5 year old granddaughter asked for this after watching show on her IPad She has learned some of her adding and times table using this

my son loves them. he plays with them for hours there are no extra stickers so he was upset when he wore out the stickers on his favorite

This is a birthday gift for my Grandson and he loves it!!!

The grandkids love the other sets so I am sure they will love this.

Such a great learning toy!

they are a great company. the products are amazing.

Good idea for kids to learn math. But manufacturers should add more white blocks to make all the numbers rectangles, the higher numbers have to share blocks (set 1-10). It is also very frustrating for my kids to make big figures because the blocks keep disconnecting if you put more pressure on them than necessary... It happens to me as an adult and it bothers me, now imagine the frustration as a child. I bought the 3 sets (1-10, 11-20, 21-30). Inevitably all the blocks got mixed up and the only solution I found is a container where everything fits in size. It bothers me that the only set that has instructions on how to put the blocks together is the 21-30 set, the rest you have to guess how to make a more or less stable figure, not to mention how helpful those instructions would be for those who only have the 1-10 and 11-20 sets. It also bothers me that the large flash cards in the 21-30 set are bigger than the other two sets. Another annoying thing is that there are only a certain number of blocks that serve as multiple connectors (and by multiple I just mean one extra male face), all blocks should have at least two male faces. Other than that, it's good to spend quality time with my kids, why do I have to be there by their side putting together the figures they want, otherwise they would be crying because they can't.
