Sensational Math™ Hands-On Tally Marks™ resemble those hand-made popsicle stick tally mark manipulatives teachers have been making for years but are made of sturdy, color-coded, molded plastic. With three tally mark styles of ones, fives and tens, these hands-on teaching aids are ready-to-use for the endless supply of math lessons teachers already use every day. The perfect size, these manipulatives are all 3. 75” high. The ones . 375” wide, fives 2. 25” wide and tens 4. 5” wide. We included a full-color teaching guide with tips and suggested lessons. The set comes in 4-color box with plastic storage tray to keep everything organized. With so many K-2 classrooms using tally mark activities in their math lessons, we also created a class set that provides oodles of Sensational Math™ Tally Marks™ for whole class activity. For centers, individualized instruction and small-group learning we have created 3 sets of full-color activity cards at 3 levels; Kindergarten, 1st Grade & 2nd Grade. These activities are self-checking and aligned to standards. Includes: Molded Plastic Tally Marks 120 each Tens, 240 each Fives, 240 each Ones, & teacher's guide
