5E Lesson Plan
Engage: Hook your students with an online bowling game to begin understanding adding and subtracting fractions of pins standing and pins knocked down.
Explore: Printable Activity for partners to practice representing addition of fractions use like denominators.
Explain: Ideas for Anchor of Support can be incorporated into interactive math notebooks.
Elaboration: Extension fraction word problem for students to use models and numerical expressions to represent adding and subtracting fractions.
Evaluation: Ideas for formative assessment to check for student mastery.
Included in Lesson:
4th grade Standards (Texas Essential Knowledge and Skills):
4.3 Number and operations. The student applies mathematical process standards to represent and generate fractions to solve problems. The student is expected to:
4.3A represent a fraction a/b as a sum of fractions 1/b, where a and b are whole numbers and b > 0.
4.3B decompose a fraction in more than one way into a sum of fractions with the same denominator using concrete and pictorial models and recording results with symbolic representations.
4.3E represent and solve addition and subtraction of fractions with equal denominators using objects and pictorial models that build to the number line and properties of operations.
4.3F evaluate the reasonableness of sums and differences of fractions using benchmark fractions 0, 1/4, 1/2, 3/4, and 1, referring to the same whole.
