solving word problems:
Learning Objectives:
3.OA.3 Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities, e.g., by using drawings and equations with a symbol for the unknown number to represent
the problem.
3.OA.4 Determine the unknown whole number in a multiplication or division equation relating three whole numbers.
3.OA.8 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 rounding.
Essential Concepts & Vocabulary:
operation, inverse operation, unknown, variable, math mountain, part, total, in all, altogether, start, change plus, change minus, end, comparison bars, comparison statement, greater than, less than, difference, left, area, array, rows, columns, total, equal, repeated groups, equal groups, number of groups, number in each group, total, situation equation, solution equation, comparison equation,
