This is an excellent resource for understanding the relationship between numbers. It helped my son master his addition facts after trying countless other curricula and approaches. We will be using the multiplication book as well.

I have no clue why there are low star ratings for this and it doesn’t seem like any of them left reviews. I’ve used this book for months now with my very bright (gifted IQ) son who has dyslexia and difficulties with math. He had NO sense of numbers, so “three” meant nothing to him and could have been dog or cat. Number words didn’t connect to fingers, so he couldn’t hear a number and put up his fingers. All the normal things you do at this age like showing the parts of 10 by moving your fingers (9 and 1, 8 and 2, etc.) meant nothing to him. What a change with Ronit Bird! Each chapter goes through very small steps, with clear pictures, showing you how to present the concepts, how to play games with the concepts, how to explore and play with them. The videos are awesome. For me the best part is using it on my ipad, since my ipad is always with me. LOVE it. What has been AMAZING to me is how many concepts have come together in my son’s mind doing such simple things. He now enjoys exploring patterns with numbers and can visualize his basic math facts up to 10 and solve simple story problems. We have a long road ahead of us, but I’m excited to continue using the Ronit Bird materials and help him continue to develop his number sense and his ability to do math! As a homeschooler I’ve used or owned almost every other math curriculum out there in the homeschool market. There’s NOTHING so detailed and careful as Ronit Bird’s materials for getting in the brain of a child with serious math issues due to dyslexia or dyscalculia. Highly, highly, highly recommend!

This is a very well-thought out book, full of ideas for helping your child if they're struggling with math — it's aimed at dyscalculic children, but the games and activities are a superb way of helping your child if they're learning basic addition and subtraction skills, whatever age they are. The videos walk you through everything you need to know as a parent for each activity, and make this far more useful than a paper edition would be.
