Instructional Time: 1 hour and 30 minutes

Mini-Lesson: How do you determine other answers that a player might think of? How would you answer the question if you did it incorrectly? Why is it better to anticipate what a player might do instead of choosing random other choices?

In Groups: Students brainstorm and add multiple answers to the question using logical reasoning (we’ve used logical reasoning in previous projects) using Multiple Choice Question Drafting Worksheet.

 California Content Standards Mathematics Grade Six Number Sense MA.6.2.0. Students calculate and solve problems involving addition, subtraction, multiplication, and division: MA.6.2.1. Solve problems involving addition, subtraction, multiplication, and division of positive fractions and explain why a particular operation was used for a given situation. Measurement and Geometry MA.6.1.0. Students deepen their understanding of the measurement of plane and solid shapes and use this understanding to solve problems: MA.6.1.1. Understand the concept of a constant such as p; know the formulas for the circumference and area of a circle. MA.6.1.2. Know common estimates of p(3.14; 22/7) and use these values to estimate and calculate the circumference and the area of circles; compare with actual measurements. MA.6.1.3. Know and use the formulas for the volume of triangular prisms and cylinders (area of base x height); compare these formulas and explain the similarity between them and the formula for the volume of a rectangular solid. MA.6.2.0. Students identify and describe the properties of two-dimensional figures: MA.6.2.1. Identify angles as vertical, adjacent, complementary, or supplementary and provide descriptions of these terms. MA.6.2.2. Use the properties of complementary and supplementary angles and the sum of the angles of a triangle to solve problems involving an unknown angle. MA.6.2.3. Draw quadrilaterals and triangles from given information about them (e.g., a quadrilateral having equal sides but no right angles, a right isosceles triangle).
