Help your students become proficient with adding and subtracting fractions with like denominators with this double set of activity cards. Fraction concepts are a major component of the Common Core State Standards for Math in the intermediate grades, and students are expected to extend their understanding of operations with whole numbers to operations with fractions. The “I Have…Who Has?” activity cards and problem solving task cards will provide your students with practice with key fraction standards in the Common Core.
Common Core State Standards for Mathematics addressed:
Number and Operations – Fractions (4.NF)
• Understand addition and subtraction of fractions as joining and separating parts referring to the same whole. (4.NF.3a)
• 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. (4.NF.3d)
Included in this bundle are:
• thirty-two “I Have…Who Has?” cards
• master list of questions & answers on all “I Have…Who Has?” cards
• thirty-two story problem task cards
• two different student task card answer sheets
• keys for both answer sheets
• two graphic reference sheets, sized to fit in your students’ math journals
Begin with the “I Have…Who Has?” cards and related journal insert. The reference sheet reviews the meanings of the terms “sum” and “difference.” Then, hand out the “I Have…Who Has?” cards, one per student (doubling up with some students if you have less than 32 students in your class). There is no designated start card – you can begin with any student as the questions and answers will loop around and lead back to whomever you chose to begin. The cards use a mix of proper and improper fractions, with some answers being fractions that can be renamed and/or reduced. The cards also feature answers in multiple forms where applicable, so your students do not need to know how to rename or reduce fractions to answer the questions. Included with the cards is a master list of all the cards’ questions and answers.
Your students can then practice applying addition and subtraction with like denominators in problem situations. Use the second journal insert to review strategies for tackling story problems. Then, have your students work in pairs, small groups, or on their own to work through the 32 task cards. [You can even use the cards for a quick game of Scoot!] The cards focus on specific denominators (3, 4, 5, 6, 8, 10, and 12) named in the Common Core Math Standards for grade 4. These denominators are the ones used on commercially-made fractions bars, fraction circles, and fraction squares. If you have these manipulatives, you can add a hands-on element to these task cards or differentiate for your more struggling learners by having your children solve the problems using those tools.
There are a variety of problem types (missing addend, finding the difference, one-step & two-step problems, etc.) to challenge your students’ problem attack skills. As with the “I Have…Who Has?” cards, the task cards mix proper and improper fractions to better emphasize with students that the rules for adding and subtracting proper fractions are the same rules used with improper fractions. Many of the answers to the story problems are improper fractions and/or fractions that can be reduced. You can choose to tell your students to simplify and /or rename any answers they find or just leave the “as is”, depending on how much work your students have done with renaming and reducing fractions already. The key shows answers in multiple forms where applicable for easier grading.

I hope your students enjoy working with these two sets of cards and become more expert with adding and subtracting fractions! – Dennis McDonald
