What's included?
* One independent practice page for each number 11-20 (see thumbnail example) and one "Number Match" worksheet,
* Answer sheet for each page (makes it easy to have parent volunteers or older students check the work for you! Also makes this great for a self-directed, self-checking Math center!)
* 72 flash cards (numbers 11-20, tens and ones models 11-20, ten frame models 11-20, 10 + __ for numbers 11-20, rekenreks for numbers 11-20, coins (dimes and pennies) for numbers 11-20, and dice for numbers 11 and 12).

*NEW 9/26/15 MATH WORK MATS Laminate or slip into page protectors to create a dry erase surface. Pair with dry erase markers and math manipulatives. Beans (two colors) would work great for students to show the number on the rekenrek! Great for Math RTI, Math centers, Morning Work, parent volunteers, cross-age tutors, early finishers, daily whole group review, and more!

Update September 2015
* I have darkened the snap cubes on the student worksheets for better printing
* I have added Math Work Mats
* I have added rekenrek and coin (dimes and pennies) flash cards in color only
* I have made the existing flash cards available in ink-saving black and white (does not include rekenreks or coin flash cards)

* Corrected missing black and white flash cards (thank you for pointing this out to me Lauri!)
* Added interactive notebook section for beginning learners (5 pages)
* Added exit tickets for each number 11-20 (half sheet, 5 extra pages)
