Worried how your wiggleworm will learn to write his numbers? Let a funny crab, a fat juicy caterpillar, a smiling snowflake and a fluffy spider teach him. With Yum Yum Numbers your child will learn to write numbers and count to 99!

This “smart” app is so cheery and full of positive reinforcement and encouragement, kids will view tracing as a game. They have a choice of scratching out numbers on a frosty window, munching through leaves to get to a shiny red apple or trace numbers on the sand and on the pumpkin.

After completing a series of numbers kids earn a reward which may be helping the caterpillar turn into a beautifully decorated butterfly, making a snowflake from jewel-like ice crystals. What little ones won't realize is even these 4 mini-games are building their motor skills and helping develop the control they will need to write.

Best of its kind.

This product is wonderful for helping preschoolers to learn their numbers both counting and writing. The only reason I give this app 4 stars is because it only goes up to 10. It would be far more beneficial for it to go to 25 or 30.
I've used this with my three year old at home and at my school with kids ages three to six to help with practicing their number sense.
I have tried countless other apps both free and paid and this is by far the best one around .

The app was very helpful for my 4-year-old preschooler! Love how the starting points are emphasized with the spider! The last exercise if a bit challenging so we switched to the easy mode.

Well done!

Nice that kids can select the character tontrace letters with. Though the snowflake is my daughter's favorite, she is havinf fun with the spider now and is practicing writing a lot to earn a game with a pumpkin (great for Halloween).
