Activity Description: In "Square Fractions", students are learning how to use different strategies to solve a problem. You will reinforce the concept of a fraction and the meaning of equivalent fractions. and illustrate operations with fractions using geometric models. Work through the activity in order, following the folding and cutting directions carefully. If scissors are not used, fold and crease the paper sharply so that it will tear cleanly. Fold the square as shown and cut or tear along the fold to divide t - insere two congruent parts. 1. Each triangle is what fraction of the original square? 1. 1/2of the original square. Pick one of the two triangles and fold it as shown. Cut or tear along the fold and ravorum two triangles 1 and 2 . 2. Triangle 1 is what fraction of: a) triangle A?/2 b) the original square? Explain your answers.
In the remaining large triangle, fold the vertex of the right angle to the midpoint of the longert side. Cut along the fold and tabel the potygons B and 3 as shown. 3. Triangle 3 is what fractional part of a) triangle 1? 112 b) triangle A? 1/4 c) trapezoid B? 113 moly gome col aract 4 . 4.

Parallelogram 7 is what fractionnl part of a. square 5? b. traperoid B? c. triangle 1? d. original square? 10. Explain how triangle 1. triangle A. and the original squne can be used to illustrate that 42​ is equivalent to 21​. 11. Explain how these figures can be used to illustrate that 21​ of 21​ is 41​. which is the multiplication problem 21​×21​=41​. 12. If the original square is one unit. explain how trapezoid D and triangle 3 can be used to model the addition problem 163​+81​=165​ 13. If trapezoid B is one unit. explain how triangle 4 and trapczoid D can be used to moclel the division problem 21​÷61​=3
