"Time Flies" telling time/clocks freebie (from Tunstall's Teaching Tidbits) - can be adapted for any grade by changing the time cards based on your standards (quarter, half, whole hour or even five minute intervals)
FREE! Roll, Write, Tally and Show can be used during center time or in small group. This activity helps students to recognize numbers on a dice as well as different ways to represent the number. Helps students to improve number sense of numbers 1-6.
Ideas for using simple number cards and math manipulatives on-hand to learn various place value concepts in first grade. It has ideas that can be expanded to other elementary grades or differentiating instruction. I really like some of the ideas from the first tip for math centers! Includes some freebies too!
