Each online lesson begins by introducing and modeling a mathematical concept. The child then completes a wide range of activities to practice the new skill. These activities present the content in many different ways, so children learn to use and apply each new skill in a variety of book is designed to supplement the online program with more exercises in the core mathematical concepts.

5 Each unit focuses on a topic within the main learning strand, presenting a series of pen and paper activities, word problems, puzzles, and games to practice their skills and understanding. The topics in this book align with the following components of the State Standards:3. N BT. A . 3 Multiply one-digit whole numbers by multiples of 10 in the range 10-90 using strategies based on place value and properties of Interpret products of whole Interpret whole-number quotients of whole Use Multiplication and Division within 100 to solve word problems in situations involving equal groups, arrays, and measurement Determine the unknown whole number in a Multiplication or Division equation relating three whole numbers. Apply properties of operations as strategies to multiply and Understand Division as an unknown-factor problem.

6 Fluently multiply and divide within 100, using strategies such as the relationship between Multiplication and Division or properties of operations. By the end of GRADE 3, know from memory all products of two one-digit Solve two-step word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including . O A . Identify arithmetic patterns (including patterns in the addition table or Multiplication table), and explain them using properties of operations. 1 Skip countingMultiplication2 How many?
