Standard MCC.3.OA.1 Interpret products of whole numbers, e.g., interpret 5 ? 7 as the total number of objects in 5 groups of 7 objects each.
MCC.3.OA.2 Interpret whole-number quotients of whole numbers, e.g., interpret 56 ? 8 as the number of objects in each share when 56 objects are partitioned equally into 8 shares, or as a number of shares when 56 objects are partitioned into equal shares of 8 objects each.

Standard MCC.3.NBT.3 Multiply one-digit whole numbers by multiples of 10 in the range 10?90 (e.g., 9 ? 80, 5 ? 60) using strategies based on place value and properties of operations.
MCC.3.MD.3 Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories. Solve one- and two-step "how many more" and "how many less" problems using information presented in scaled bar graphs. For example, draw a bar graph in which each square in the bar graph might represent 5 pets.

Notes
This standard expects that students go beyond tricks that hinder understanding such as "just adding zeros" and explain and reason about their products. For example, for the problem 50 x 4, students should think of this as 4 groups of 5 tens or 20 tens. Twenty tens equals 200.
