Put down those calculators! Show scholars they can solve division problems mentally using rounding strategies. They divide four-digit dividends by one-digit divisors, competing 26 problems in all. The first eight have some scaffolding...

In this multiplication estimating worksheet, students solve 40 problems in which products of two digits are estimated, then calculated. This page is intended as an online activity, but may be completed on paper.

Measuring length with nonstandard units is the focus of this word problem learning exercise. Youngsters problem solve using cubes, paper clips, footprints, and pencils. They solve six problems.

In this estimating sums and differences practice worksheet, students sharpen their problem solving skills as they solve 6 story problems.

Through estimating, scholars are able to make these word problems simpler as they multiply to find approximate answers. Using an example as guidance, they solve five scenarios, each of which has space for learners to show their work. The...

Try to find an estimate when the exact answer is not clear. Using the General Certificate of Secondary Education Math review resource, pupils learn how to find an estimate to a cubic equation. Class members use the trial-and-improvement...

Use fractions to estimate candy counts. After watching a video of emptying a bag of candies into a glass, individuals estimate the number of candies of each color. The teacher provides the class with additional information to help answer...

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...

Introduce learners to two methods to estimate the formula for the area of a circle. The first method uses a sector of a circle to form a rectangle, and the other uses grids to estimate the area. The problems in the 18th segment of a...

The more rectangles, the better the estimate. Using the interactive, pupils explore estimating the area under a curve using left-hand sums. Learners respond to challenge questions on how to get better estimates using the same technique.

Profit always seems to get everyone's attention. The same is true during a instructional activity on estimation. Learners use given information to estimate the cost of supplies for a painting job. They then develop a strategy for...

Let's find a way to determine how many there are. Given a diagram of trees on a plantation, pupils devise a way to estimate the number of old and new trees. Using their methods, learners create estimates for the number of the two types...

There are several ways to estimate the area if the curve does not create nice geometric figures. The presenter introduces the idea of using areas of rectangles to estimate the area under the curve. Pupils use four types of Riemann Sums,...

Take your best educated guess. After being presented with a video of a glass of candies, class members estimate the number of each color of candies. Pupils view a graphic showing more information on the fraction of candies before...

Use volume to count your change. Pupils watch as a cube is filled with stacks of pennies and make an estimate on how many pennies are in the cube. The teacher provides additional information to the class members about the size of the...

Wonder how many pieces of candy a teacher can eat. Pupils watch a video of candy in a bowl as some candy is removed to be eaten and others are added. Learners devise questions about the situation along with estimated solutions. Scholars...

Have you ever examined a pumpkin and estimated the number of lines it has? In this math lesson, students count the actual number of lines, record and graph the results. They investigate the circumference, weight and buoyancy of the...

Using the provided blank face template, learners of any age draw to learn how to create proper facial proportions. This lesson focuses on two dimensional facial proportions, how to estimate those proportions, and drawing techniques. If...

Microbiology beginners feed different sweetening agents to yeast and measure carbon dioxide production to estimate energy contained in each. They set the trials up in zip-top plastic baggies and then measure gas volume by water...

First graders estimate length and height of items. They read the story of Jack and the Beanstalk and discuss estimation of size. Students predict the length and height of figures. They use lines and numbers on the centimeter rod and tape...

Students research the HPV vaccine and estimate its cost. They interview doctors and local health officials about it. Students write feature stories based on their research focusing on the timelines for implementation in their states or...

Young geometers explore relationships between units of measure and objects. Three activities provide varied opportunities to practice. Learners calculate the volume of two cylinders made by rolling a piece of paper vertically and...

In this holiday worksheet, students estimate how many heart candies are in a cup. Then, students sort their hearts and add up how many are in each color and how many there are total. Students also create a bar graph that displays how...

An interactive assignment displays two example angles to teach how to measure them. When you click on the angles, a protractor appears! As practice, learners view a set of angles, estimate the size of each, and then enter the degrees in...
