Debi Godfrey provides activities with pan and number balances to represent and build the concept of equality in kindergarten.

Comparing and Ordering Fractions (grades 2-3)
Laura Scearce models the use of an instructional card game to reinforce the concept of comparing fractions.

Models for Teaching Fractions (grades K-2)
Laura Scearce highlights key concepts that should be addressed when providing instruction on fractions.

Computation & Estimation

Strategies for Learning Basic Facts (grades K-3)
Laura Domalik discusses the instructional strategy of doubles for developing basic facts concepts (1+1, 2+2,...10+10) that are found in the real word using the game "Doubles Cover Up."

 Array Model for Multiplication (grades 3-8)
Jennifer Jones connects the use of the array model for multiplication of whole numbers to multiplication of mixed numbers and then to multiplication of binomials in algebra.
