Watch the damage from a forest fire in this interactive simulation activity that challenges learners to estimate the burn area using different approaches. Learners are given a worksheet to track the different burn patterns and practice...

Teach your class a thing or two about making educated mathematical guesses. Learners read a passage that explains estimation and approximate and exact answers. They then respond to five questions about and related to the text.

Heads! A great way to practice probability is to flip a coin in class. The provided data allows your mathematicians to predict the probability of heads in ten coin flips. Bring coins to class and allow your own trial of heads or tails....

Help mathematicians estimate how many seeds are in a given vegetable or fruit. They are divided into pairs and estimate the amount of seeds in a whole fruit without seeing the inside. They then cut the fruit or vegetable in half and...

In this estimation worksheet, learners read a word problem about the Lincoln Memorial and then answer 4 fill in the blank questions where they decide whether they need to use an exact number or an estimate to answer each question.

Students solve problems using estimation and exact calculations. In this algebra lesson plan, students use gum balls and thread to create hands on manipulatives to solve problems. They calculate the average of their total data.

In this writing math problems worksheet, 3rd graders write four math problems involving three toy store scenarios stated on the worksheet. Students determine if they are an estimate or an exact solution to the problems.

Help pupils explore estimation. They will make estimates and discuss when you might use an estimate. Then they discuss if their estimates are reasonable.

The more you know, the more you can learn. Scholars apply the double angle and half angle formulas to determine trig values based on known values. They use an interactive that provides sine and cosine values to aid calculations.
