Description

Protractor Practice- You Name It! Crack the Code is a fun, yet challenging activity that is loaded with mental math and problem solving opportunities. 25 problems are included and 19 of those are needed to crack the code. Students will need to have a strategy to read the angle when one or both of the rays don’t entirely reach the protractor's edge.

Please Note: These activities are designed to give students practice reading angles, not measuring them with real protractors. They need to use the protractor provided, and devise a way to extend the rays that do not touch that protractor. The problem solving has them adding and subtracting to find the measurements, using what they know about acute and obtuse angles.

Each Protractor Practice activity has several rays all starting in the same place, which muddies the point of origin, leading to inaccurate measurements, if students try to use a real protractor.

CCSS4.MD.C.5

Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement:

Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.

Make sense of problems and persevere in solving them. Mathematically proficient students start by explaining to themselves the meaning of a problem and looking for entry points to its solution. They analyze givens, constraints, relationships, and goals. They make conjectures about the form and meaning of the solution and plan a solution pathway rather than simply jumping into a solution attempt. They consider analogous problems, and try special cases and simpler forms of the original problem in order to gain insight into its solution. They monitor and evaluate their progress and change course if necessary. Older students might, depending on the context of the problem, transform algebraic expressions or change the viewing window on their graphing calculator to get the information they need. Mathematically proficient students can explain correspondences between equations, verbal descriptions, tables, and graphs or draw diagrams of important features and relationships, graph data, and search for regularity or trends. Younger students might rely on using concrete objects or pictures to help conceptualize and solve a problem. Mathematically proficient students check their answers to problems using a different method, and they continually ask themselves, "Does this make sense?" They can understand the approaches of others to solving complex problems and identify correspondences between different approaches.
