Your students will love practicing what they have learned about writing/translating verbal expressions into algebraic expressions with this engaging, hands-on activity. Students will cut out the double tangram puzzle pieces, find corresponding expressions, and finally put all the pieces together to make a fun picture of a lion. If you choose to make it artsy, you can have your students glue the pieces to a sheet of paper, then color and decorate their pictures. Enjoy!
This activity addresses the Common Core Standards 5.OA.A.2 and 6.EE.A.2., but may also be relevant to other grade levels depending on your district's curriculum.
Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them. For example, express the calculation "add 8 and 7, then multiply by 2" as 2 × (8 + 7).
Write, read, and evaluate expressions in which letters stand for numbers.
Write expressions that record operations with numbers and with letters standing for numbers. For example, express the calculation "Subtract y from 5" as 5 - y.
Identify parts of an expression using mathematical terms (sum, term, product, factor, quotient, coefficient); view one or more parts of an expression as a single entity. For example, describe the expression 2 (8 + 7) as a product of two factors; view (8 + 7) as both a single entity and a sum of two terms.
