Add & Subtract Fractions with Like Denominators
In this activity, Carl, the half-man, half-robot from the future, has a problem with his Size Ray. Students add and subtract fractions using a linear model, on a number line, and using an equation as Carl solves the problem. Jillbot to the rescue!
8 problems that tell a story and include addition & subtraction of fractions and mixed numbers
Use with the whole class, during guided math, with small groups, in centers, or in tutoring or intervention.
This activity includes clear and concise teacher directions,an example with questioning, an answer key, and conversation starters that give students what they need to have meaningful academic discussions.
Common Core Curriculum alignment
Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.
Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation. Justify decompositions, e.g., by using a visual fraction model. Examples: 3/8 = 1/8 + 1/8 + 1/8 ; 3/8 = 1/8 + 2/...
Add and subtract mixed numbers with like denominators, e.g., by replacing each mixed number with an equivalent fraction, and/or by using properties of operations and the relationship between addition and subtraction.
Solve word problems involving addition and subtraction of fractions referring to the same whole and having like denominators, e.g., by using visual fraction models and equations to represent the problem.
TeachTransform creates fun math activities that get students involved in real math. We bring decades of education experience to the task, and we believe that students learn best when teachers and students are having fun.
