### Description

Have your students apply their understanding of PYTHAGOREAN THEOREM with these ERROR ANALYSIS activities.

Giving students opportunities to identify and correct errors in presented solutions allows them to show their understanding of the mathematical concepts you have taught.

This resource includes 10 real-world PYTHAGOREAN THEOREM word problems that are solved incorrectly. Students have to IDENTIFY THE ERROR, provide the CORRECT SOLUTION and share a helpful STRATEGY for solving the problem. An ANSWER KEY has also been provided with examples of possible answers. Be sure to download the sample for a full overview of what you get.

When I present this activity to my students, I tell them that these are errors that students from my other class made and I need their help to correct them. Students LOVE correcting other students mistakes. Students can use these activities with a partner, as a warm-up , as classwork, homework, in math centers or group work.

CCSS8.G.B.7

Apply the Pythagorean Theorem to determine unknown side lengths in right triangles in real-world and mathematical problems in two and three dimensions.

CCSSMP3

Construct viable arguments and critique the reasoning of others. Mathematically proficient students understand and use stated assumptions, definitions, and previously established results in constructing arguments. They make conjectures and build a logical progression of statements to explore the truth of their conjectures. They are able to analyze situations by breaking them into cases, and can recognize and use counterexamples. They justify their conclusions, communicate them to others, and respond to the arguments of others. They reason inductively about data, making plausible arguments that take into account the context from which the data arose. Mathematically proficient students are also able to compare the effectiveness of two plausible arguments, distinguish correct logic or reasoning from that which is flawed, and-if there is a flaw in an argument-explain what it is. Elementary students can construct arguments using concrete referents such as objects, drawings, diagrams, and actions. Such arguments can make sense and be correct, even though they are not generalized or made formal until later grades. Later, students learn to determine domains to which an argument applies. Students at all grades can listen or read the arguments of others, decide whether they make sense, and ask useful questions to clarify or improve the arguments.

CCSS8.EE.A.2

Use square root and cube root symbols to represent solutions to equations of the form ๐นยฒ = ๐ฑ and ๐นยณ = ๐ฑ, where ๐ฑ is a positive rational number. Evaluate square roots of small perfect squares and cube roots of small perfect cubes. Know that โ2 is irrational.
