4th Grade March - April

March-April Adding and Subtracting Fractions, and Multiplying a Whole Number by a Fraction Manipulatives and Visual Models for all! Use word problems to introduce: Add and subtract fractions with like denominators Decompose fractions into its parts (6/4 = 4/4 + 2/4 or 1 and 2/4) (make sure to include fractions greater than one and mixed numbers for students to rename) Add and subtract mixed fractions by decomposing fractions (using understandings of fractions greater than one) Make a line plot to display data of measurement in fractions of a unit (1/2, ¼, 1/8) and solve addition and subtraction problems by using information in the line plot. Relate addition (groups x how many in a group) and subtraction (decomposing) to multiplication (whole number x fraction)
