Description

Pi Day Crack the Code gives students practice solving for radius, diameter, circumference and area of a circle with 2 Crack the Code puzzles. These self-correcting puzzles offer built-in practice with rounding decimals. Teacher notes and answer keys are included.

Also included, an interactive notebook page for finding area and perimeter of circles for reference. This page makes a good introductory piece or a reminder of how 3.14 relates to area and perimeter of a circle.

These problems are designed to help students practice using the rules and understanding the relationships between radius, diameter and circumference.

Pi Day: Area and Perimeter of a Circle makes a good calculator problem. There are multiple steps to the problems and it makes them think about the accuracy of their input.

The first puzzle, Finding Circumference, Diameter, & Radius encourages flexible thinking as students solve the different problems, while giving one of the three measurements.

The second puzzle, Finding Area of a Circle- Crack the Code gives students diameter and radius measurements, solving for the area of each of the circles.

CCSS7.G.B.4

Know the formulas for the area and circumference of a circle and use them to solve problems; give an informal derivation of the relationship between the circumference and area of a circle.

CCSSMP1

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.

CCSSMP6

Attend to precision. Mathematically proficient students try to communicate precisely to others. They try to use clear definitions in discussion with others and in their own reasoning. They state the meaning of the symbols they choose, including using the equal sign consistently and appropriately. They are careful about specifying units of measure, and labeling axes to clarify the correspondence with quantities in a problem. They calculate accurately and efficiently, express numerical answers with a degree of precision appropriate for the problem context. In the elementary grades, students give carefully formulated explanations to each other. By the time they reach high school they have learned to examine claims and make explicit use of definitions.
