Title: Pizza Problems: An Angle Investigation
Description:
This investigative lesson allows students to identify angle measurements as part of a larger angle. Students will deconstruct 180 degree angles into equal parts.
This is a College and CareerReady Standards showcase lesson plan.
Standard(s): [MA2015] (4) 25: Recognize angle measure as additive. When an angle is decomposed into nonoverlapping parts, the angle measure of the whole is the sum of the angle measures of the parts. Solve addition and subtraction problems to find unknown angles on a diagram in realworld or mathematical problems, e.g., by using an equation with a symbol for the unknown angle measure. [4MD7]

Title: Go Bananas over Angles!
Description:
Banana Hunt is an online interactive activity that can be used in a wholeclass setting, cooperative groups, small groups, or with individuals. This fun website will have your students going "bananas" over recognizing angles. The interactive game ask, "How many bananas can you find in 10 searches?". The game has a large circle with an angle with a monkey on the end of one of the rays. Students will drag the monkey(ray) to the location of the banana by creating the correct angle. Students will press "search". If the students find the right location(angle) on the circle of the banana they will receive 10 bananas.

Title: Communicating about Mathematics Using Games: Playing Fraction Tracks
Description:
Mathematical games can foster mathematical communication as students explain and justify their moves to one another. In addition, games can motivate students and engage them in thinking about and applying concepts and skills. This eexample from Illuminations contains an interactive version of a game that can be used in the grades 35 classroom to support students' learning about fractions. eMath Investigations are selected eexamples from the electronic version of the Principles and Standards of School Mathematics (PSSM). The eexamples are part of the electronic version of the PSSM document. Given their interactive nature and focused discussion tied to the PSSM document, the eexamples are natural companions to the iMath investigations.
