Reinforce number sense with a collection of math lessons for kindergarteners through fifth graders. Young mathematicians take part in hands-on activities, learning games, and complete skills-based worksheets to enhance proficiency...

Multiplication on the fly becomes easy with the magic of estimating! Scholars round numbers up to four digits to complete multiplication problems without a calculator. They write in the new factors and the approximate product for the...

Sometimes simple is just better. A set of activities teaches young mathematicians about using plausible estimation to solve problems. They break problems down to simpler problems, use rounding and estimation strategies, and consider...

Investigate how rounding affects values. Individuals watch a video about how to find the highest and lowest possible numbers that result in a given value when rounded to a certain place value. They finish by completing a worksheet of...

A 33-page packet focuses on fifth-grade math concepts. Learners practice rounding numbers to the hundred thousands, thousands, hundreds, tens, ones, hundredths, thousandths, and hundred thousandths. They also compare whole...

Estimating whole number multiplication and division is the focus of an interactive that uses a garden plot with moveable points to answer six questions.

Show the knowledge learned about decimals. A short assessment covers the material presented in the first half of the unit. Pupils demonstrate their knowledge of comparing, rounding, and multiplying and dividing by powers of 10 with...

Learners round three-digit and four-digit numbers to the nearest hundred. They solve 10 problems.

Explore all things decimal in this thorough series of introduction activities. Including scripting for the teacher and detailed descriptions and examples, the plan begins by reviewing the basics of place value and writing fractions as...

Common denominators, factors, and rounding are a few of the terms in a set of flash cards designed to reinforce math vocabulary. Forty-two cards offer a bold-faced vocabulary word or a corresponding definition alongside an...

The story, How Many Jelly Beans? by Andrea Menotti introduces a lesson about partial quotients. Mathematicians practice rounding and multiplying, then work in small groups to connect those skills with division and partial...

In this estimating practice worksheet, students sharpen their math skills as they learn how to make likely estimates and try the 2 extra practice activities.

Pupils investigate various types of problems using whole numbers and decimals. They use a discussion format while working example problems to help create a baseline for further independent practice. The lesson also includes praise for...

It seems like it should be about three. Pupils learn to get an estimate of the derivative of a function at a point by using the derivative functionality of their graphing calculators. They take that information to determine the equation...

In this estimating numbers on a number line instructional activity, students estimate the 8 whole numbers that the arrows are pointing to on 4 number lines.

In this rounding worksheet, learners round a set of 40 numbers to the nearest 100. An answer key is included. A website reference is given for additional resources. 

In this estimating worksheet, students estimate the whole numbers that arrows on a number line are pointing to, 0-10. A website reference for additional activities is given.

Young mathematicians round numbers to the nearest 100. They round 10, 3 digit numbers to the nearest 100. Good, basic practice

In this estimating time worksheet, 2nd graders solve 6 problems in which the time it takes to perform a specific task is estimated. Students choose an estimate from two answers.

What is a quick comparison, and how can it help you estimate sums and differences? For this estimation worksheet, learners estimate fractions in addition problems. They complete four problems where they estimate the sums after reviewing...

Looking for an estimation activity a bit more involved than the typical "guess the number of jellybeans in the jar" game? Here, learners use a picture to estimate the number of people at a large event, look for potential problems with...

We know that sample data varies — it's time to quantify that variability! After calculating a sample mean, pupils calculate the margin of error. They repeat the process with a greater number of sample means and compare the results.

What if you don't have theoretical probabilities with which to create probability distributions? The 11th installment of a 21-part module has scholars collecting data through a survey. The results of the survey provide empirical data to...
