Options include using 10, 15, or 20 number tiles and designating a range of beginning numbers.

Includes options in the iPad version to designate the beginning number as well as setting options to worth with hundreds and negative numbers.

Ratings and Reviews

Excellent number skills and fine motor!


This is a great app to help with learning numbers and ordering them properly. Also has the added bonus of working on fine motor skills. This app keeps my daughter as well as my students with special needs busy and learning at the same time. Would definitely recommend--and you can't beat the price!! Would be cool if you could go up to 100 all at one time as well as learn each block of 10-20 numbers to 100 in increments. Thanks for keeping us learning!!

Great Skill Building


I think this is an easy and concrete app to work on number order. My updated version shows numbers through 199. Much more practical to use than manipulatives and it is a quick skill building exercise. I would love to see more like this.

Would like to have it say the number


I would like the option for it to say the number when you put it in the line. Great app for practicing numbers. I am glad you added tiles up to 100. Would be neat to see all 100 at once.
