In a six-problem learning activity, children are guided to solve word problems that involve rounding to the nearest ten and nearest hundred. A commentary and answer key provide different approaches that learners may take in solving the...

Don't be irrational! Use this pre-test to assess your classes' ability to work with all types of real numbers. The lesson asks learners to estimate value, evaluate roots, and order numbers. This begins a series of lessons on the real...

Trying to get your class to think of decimals as fractions and vice versa can lead to interesting discussions. After all, we can usually understand quickly that 1/4 is .25 but why is 1/7 not so easy to convert? This activity looks...

Boiling down any division problem to a one-digit divisor problem sure makes estimation easy. The instructional activity shows how to estimate division problems by using place value understanding and basic arithmetic facts to simplify the...

Take a spin to determine experimental probability. Small groups spin a spinner and keep track of the sums of the spins and calculate the resulting probabilities. Pupils use simulated frequencies to practice finding other probabilities to...

Have scholars show what they know with a 20-page assessment aligned to the California State Standards. The test covers concepts such as large and whole numbers, all four mathematical operations, fractions, decimals, geometric figures,...

Work it out — find the average time clients spend at a gym. Pupils use a table of random digits to collect a sample of times fitness buffs are working out. The scholars use their random sample to calculate an estimate of the mean of the...

The purpose of this task is for students to practice rounding numbers to the nearest ten, connect the rules for rounding with location on the number line, and to introduce the idea of rounding to the nearest 100. Aligns with...

Practice your rounding skills in this online quiz. There are ten questions, and you select the correct answer by rounding to the nearest tenth.

This task builds off of the skill of rounding to the nearest ten and hundred in third grade. Aligns with CCSS.Math.Content.3.NBT.A.1 Use place value understanding to round whole numbers to the nearest 10 or 100.

Students explore different rounding scenarios. Aligns with CCSS.Math.Content.3.NBT.A.1 Use place value understanding to round whole numbers to the nearest 10 or 100.

Round each number to the nearest hundred. Select the correct answer of three choices. There are ten random questions.

Practice comparing two real-world quantities by approximating them using rounding and powers of 10. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

This resource covers whole number rounding where students can choose to round to the nearest tens to millions. After selecting parameters students are timed completing ten problems with instant feedback and an opportunity to practice again.
