Using a Calculator (A) WORKSHEET
Suitable for Grades: 8th Grade
CCSS: 8.NS.A.2
CCSS Description: Use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximately on a number line diagram, and estimate the value of expressions (e.g., π2). For example, by truncating the decimal expansion of √2, show that √2 is between 1 and 2, then between 1.4 and 1.5, and explain how to continue on to get better approximations.
Using a Calculator (A) WORKSHEET DESCRIPTION
This worksheet encourages students to use calculator functions and buttons to carry out operations such as multiplying by pi, squaring/square rooting, fraction arithmetic, negative number operations, and more.
In section A, students will write down the full calculator display to seven questions such as 4.9^2. Then in section B, students will answer eight word problems, considering how to use their calculator to do so.
Learners need to be able to find fractions of amounts, calculate difference, and solve direct proportion problems.
