Learning Domain: Measurement and Data

Standard: Solve problems involving customary measurement: Estimate and measure lengths in customary units to the quarter-inch and half-inch, and feet and yards to the whole unit; Estimate and measure capacity and weight in customary units to a whole number: cups, pints, quarts, gallons, ounces, and pounds; Add, subtract, multiply, or divide to solve one-step word problems involving whole number measurements of length, weight, and capacity in the same customary units.

Learning Domain: Measurement and Data

Standard: Represent and interpret scaled picture and bar graphs: Collect data by asking a question that yields data in up to four categories; Make a representation of data and interpret data in a frequency table, scaled picture graph, and/or scaled bar graph with axes provided; Solve one and two-step "how many more" and "how many less" problems using information from these graphs.

Learning Domain: Measurement and Data

Standard: Relate area to the operations of multiplication and addition: Find the area of a rectangle with whole-number side lengths by tiling it, and show that the area is the same as would be found by multiplying the side lengths; Multiply side lengths to find areas of rectangles with whole-number side lengths in the context of solving problems, and represent whole-number products as rectangular areas in mathematical reasoning; Use tiles and/or arrays to illustrate and explain that the area of a rectangle can be found by partitioning it into two smaller rectangles, and that the area of the large rectangle is the sum of the two smaller rectangles.
