In this estimation worksheet, students estimate a set of 10 numbers to the nearest 10. A reference website for additional resources is given.

Students apply estimation strategies and proportional reasoning to determine a scale comparing the planetary bodies to Earth. They convert measurements of time and distance using scientific notation. Both the metric and customary units...

Students estimate and record the number of raisins in a snack-size box. They also graph their results and note the differences (+ or -) from their estimate and actual number.

First graders, in groups, try to figure out which box of name brand raisins have more.

Second graders flip coins and tally the outcomes. They play the You May Already Be a Winner! game with cards under their chairs. Some cards are winners, some might be and the others are not. They play to explain the probability concept.

Students use powers of ten to make reasonable estimations for list of questions. They share their problem solving techniques with the class.

Fifth graders review adding, subtracting, multiplication and division of fractions and decimals through a variety of activities and exercises.

Eighth graders analyze how to use statistics, change fractions to decimal, and graph their statistics. They draft players from Major League Baseball eams and chose on player for each position, including 3 oufielders and one designated...

Students make a rocket out of paper. They follow the given instructions and test to see if it will fly. They write about the experiment and are given the opportunity to change their varibles to make their rocket work.

Learners solve word problems using number sense. They convert fractions to decimals and mixed numbers. Pupils determine if a given fraction is greater or less than another fraction, and order numbers on a number line.

Kids gain a deeper understanding of mathematical symbols, by playing an interactive game using flash cards. They complete an attached Missing Symbols Worksheet, flash card and an assessment are also included.

With minimal setup and maximum freedom, young geometers are encouraged to think outside the box on a seemingly simple application problem. Though the task seems simple, measuring a given paper clip and finding how many 10 meters can...

Lead a discussion on the similarities between the properties of area and the properties of volume. Using upper and lower approximations, pupils arrive at the formula for the volume of a general cylinder. 

Reduce variability for more accurate statistics. Through simulation, learners examine sample data and calculate a sample mean. They understand that increasing the number of samples creates results that are more representative of the...

Mathematicians need to know that not all numbers are rational. We approximate irrational number with rational numbers. That is why a calculator may be misleading. This task give learners an opportunity to see how rounding a number and...

Exactly how fair are the board games children grow up playing? Young mathematicians investigate this questions as they work their way through this five-lesson series on basic probability. 

If we stack up all the cross sections of a figure, does it create the figure? Pupils make the connection between the complete set of cross sections and the solid. They then view videos in order to see how 3D printers use Cavalerie's...

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...

Increase your sample and increase your accuracy! Scholars complete an activity that compares sample size to variability in results. Learners realize that the greater the sample size, the smaller the range in the distribution of sample...

It's scary how fast bacteria can grow — exponentially. Class members solve exponential equations, including those modeling bacteria and population growth. Lesson emphasizes numerical approaches rather than graphical or algebraic.

Learners explore volume in relation to centimeter cubes and other nonstandard units of measurement using small containers. They will use hands-on materials to practice this concept. You will need small objects and containers to set this up.

Students experiment with reflections of two plane mirrors placed at a 90 degree angle to see what will be reflected.

Third graders determine the outcome of each of the following situations and justify their findings: even number + even number = ?, even number + odd number = ?, odd number + odd number = ?, and odd number + even number = ?.

This thirteen page data analysis worksheet contains a number of interesting problems regarding statistics. The activities cover the concepts of average measurements, standard deviation, box and whisker plots, quartiles, frequency...
