MAFS.4.NF.2.AP.3c Match the vocabulary in a word problem to an action. Use manipulatives to model the context of the word problem. Count to find the answer. To add, use fraction manipulatives (each piece may be labeled with the corresponding unit fraction) to model each fraction and join them to find the sum (e.g., 1/4 + 2/4 = 3/4). To subtract, use fraction manipulatives (each piece may be labeled with the corresponding unit fraction) to model the first fraction in the expression and remove manipulatives that represent the fraction being subtracted (e.g., ¾ - 2/4 = 1/4). Create a pictorial representation of the word problem. Use context clues to interpret the concepts, symbols, and vocabulary for addition and subtraction. To add, use a visual representation of a whole divided into equal pieces (each piece may be labeled with the corresponding unit fraction). Shade each unit to represent the fractions in the expression and count the shaded units to find the sum. To subtract, use a visual representation of the first fraction in the expression. Cross out the piece(s) that represent the fraction being subtracted. Count the remaining piece(s) to find the remainder. Suggested Instructional Strategies: Model Materials Teacher Says/Does Student Response Teacher Feedback Teacher: Fraction Bars “I can use fraction bars to add fractions.” Lay down fraction bars. Point to and name each fraction separately. (E.g., for the addition expression 1/4 plus 1/4, lay down (2) 1/4 pieces Student watches. “Good, watching me.”
