Power Corrections Answer Key
About This Worksheet
This worksheet asks students to decide whether statements about powers of ten are true or false. When a statement is false, students must rewrite it so that it becomes correct. For example, 104 does not mean 10 x 4 because it represents four factors of 10 multiplied together. This format helps students check whether they truly understand powers of ten rather than only memorizing procedures.
Curriculum and Grade Alignment
This activity is designed for fifth-grade math and reinforces CCSS.MATH.CONTENT.5.NBT.A.2. Students should already know how to write powers of ten, multiply by them, divide by them, and explain how digits shift in place value. The next step is using that knowledge to evaluate mathematical statements and explain why they are correct or incorrect. This worksheet builds reasoning skills along with computational understanding.
Student Tasks
On this worksheet, students will read ten statements about exponents, multiplication, division, and place value. They decide whether each statement is true or false and then correct any false statement. Some items focus on exponent meaning, while others check multiplication or division by powers of ten. Students also review general rules about how digits move when values become greater or smaller.
Common Challenges
Some students may mark an item false but have trouble rewriting it correctly. Others may confuse the exponent with ordinary multiplication, especially in statements such as 104. Place-value statements can also be tricky because students may mix up which direction digits shift. Teachers can help by asking children to explain the rule in their own words before deciding whether each statement is true or false.
Teaching Tips
This worksheet is a strong review activity after students have completed several types of powers-of-ten practice. Teachers can use the statements for class discussion before assigning the page independently. Parents can ask children to explain why each answer is true or false instead of accepting a one-word response. That extra explanation makes it much easier to spot misunderstandings that might otherwise go unnoticed.
Worksheet Features
The worksheet contains ten true-or-false statements covering several important powers-of-ten ideas. Space beside each statement allows students to rewrite incorrect examples clearly. The mix of exponent notation, standard numbers, multiplication, division, and place-value rules gives students a broad review. The page works especially well for assessment, review, intervention, or test preparation.
