Description
Help students build confidence with square roots by practicing how to estimate the value of non-perfect square roots. In this 15-card Boom Card deck, students determine which two perfect squares a number falls between and estimate the approximate value of its square root. Problems encourage students to think about square roots in relation to nearby perfect squares and place values on a number line. This deck is perfect for 8th grade math, review of irrational numbers, math centers, homework, or quick formative assessment. Students will strengthen number sense and develop strategies for approximating square roots without a calculator.
