To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
The math link cubes are great but the package must have gone through an ardous journey. The parcel came battered and torn, and the blocks spilled out of the ziplock bag that it was supposed to be beautifully packed in. (Because of how torn the parcel is we will probably get to practise counting to see if any blocks fell out of the package.) It's disappointing really because this is supposed to be a gift.
Read in reviews that the links are hard for little hands to fix and remove, but seeing how they are separated just by shipping, I'm guessing that won't be much of an issue.
Originally saw these used in a Youtube video to make numberblock crafts. Thought they would be a good learning tool for kids. Turns out the connecting ends are flimsy and would pop off easy. Each cube only has one protruding connector. Making crafts requires figuring out how to connect multiple blocks with just one side that allows for attachment.
