STANDARDS FOR MATHEMATICAL CONTENT MCC.5.OA.2 Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them. STANDARDS FOR MATHEMATICAL PRACTICE SMP 1. Make of problems and persevere in solving them. SMP 2. Reason abstractly and quantitatively. SMP 3. Construct viable arguments and critique the reasoning of others. SMP 6. Attend to precision. Background Knowledge Students should have had prior experiences writing expressions. In this task, students will practice matching an expression written as a numeric calculation to its written form in words. In order to do this, students will need to be able to use and apply the commutative and associative properties of addition and multiplication as well as the correct order of operations. They will also need to apply third grade standard MCC3.NF.1 by understanding that dividing by a whole number is the same as multiplying by a unit fraction with that whole number as its denominator. For example, one-half of a quantity is the same as dividing by two, and one-third of a quantity is the same as dividing by three. COMMON MISCONCEPTIONS Students may choose the wrong operation because they don’t fully understand the meaning of each of the four operations and the vocabulary associated with each operation. Reviewing contexts for each operation and vocabulary such as product, sum, difference, etc. before doing this activity may be helpful. Students may try to the numbers in an expression to the word forms of those numbers. The puzzle has been written with distractors that use the same numbers in different operations. Therefore, students will need to carefully consider the correct operation and order when selecting the matching puzzle piece. ESSENTIAL QUESTIONS How can an expression be written? MATERIALS Directions and questions for Expression Puzzle
