Learners access prior knowledge to round numbers and add decimals. In this mental math instructional activity, students share the book Betcha and calculate estimates for three jars based on the book. Learners calculate money answers...

Second graders identify the attributes of various shapes and estimate the weight of the objects. In this geometry lesson, 2nd graders identify the attributes of concrete objects and use a pan balance to weight them.

Students practice counting and comparing objects.  In this math lesson, students view a Count on It! episode. Students examine the value of what they are counting.  Students estimate number in groups of items.  Students...

Third graders demonstrate their estimating and measuring abilities.  In this length measurement lesson, 3rd graders produce estimates of how long a handful of French fries will be before physically measuring them.  Students...

Students participate in an experiment to understand how robotic systems can estimate distances.  In this robotic ranger lesson, students measure the the time it takes for and object to move back and forth.  Students will use a...

Students participate in a Mini-Olympics with measurements. For this measurement lesson, students throw items and predict how far they will go. They measure the actual distance and find the difference between that and their estimate. 

Fourth graders view a variety of rice products and calculate their cost.  In this rice math lesson, 4th graders estimate cost and multiply to find 8 of each item. Students estimate using different amounts of rice products. Students...

Learners practice using their estimation skills by utilizing apples.  In this percentage lesson, students utilize a scale and an apple to discover the percentage of each bite they take.  Learners share their data with the rest...

Students estimate how far they can run, jump, or hop in five seconds, then check their prediction.  In this estimation lesson, student predict how far they can run, hop, or jump in five seconds and then try it.

Fourth graders work with patterns while using large numbers. In this patterning lesson, 4th graders go over the definitions of the words: predict, estimate, attendance, increase, and decrease. They complete worksheets in which they track...

In this consumer math worksheet, students estimate and then multiply the given money amounts. Students also practice finding change. There are seven problems to complete.

Young scholars estimate the density of a population of insects (grasshoppers) at a given life cycle stage in a given type of habitat.

Students estimate the amount of money a non-smoking teen spends in a week, a month, and a year, and compare it with the expenses of a teen who smokes one, two, and three packs a day. They research other reasons that teens should not smoke.

Students collect, organize by table, and examine census data in a simulation, estimate the size of the population in the simulation and make predictions based on the collection of census simulation data.

Students study how scientists have estimated the maximum height to which trees can grow, and assess the reliability of interpolation and extrapolation techniques by making predictions with particular data sets and analyzing accuracy of...

Students estimate and calculate the sale price of five items using the original price and a designated rate of discount. They use percent to calculate the rate of discount and the original.

Students identify geometric shapes, demonstrate construction of an object graph, compare sets of objects, estimate which student has the most geometric shapes in his or her bag, and play computer game Jump Start Kindergarten.

Tenth graders explore how to use basic geometry and calculation skills to design their dream house. They use calculation to design the home and estimate the price within a budget of $150,000.

Fifth graders estimate how many M&Ms are in a pre-counted bag. They determine how many colored M&Ms are in a bag, then decide which of the two, bar graph or circle graph (in this case, circle graph) would be best to show te results.

Eighth graders investigate the concepts that are related to measurement while focusing upon weight, mass, and capacity. They estimate the weight and mass relationship that is found in different problems. Students compare and contrast one...

Students pan for minerals in a stream and discover why magnets attract magenitite but not nonmagnetic grains. They participate in the actual panning process and bag samples to be examined in class. Students recognize minerals by color...

Students identify the use of different types of bar graphs. They analyze graphs used in the New York Times to compare the estimated cost of the war in Iraq to other hypothetical expenditures and reflect on how graphs can help illustrate...

Students review the units of the metric system, convert from the US system of units of measure to the metric system, and estimate measures before converting between the two systems of measurement.

Young scholars investigate the age of the earth by using accepted scientific methods. They conduct research about the use of radioactive dating and there is a simulation activity of the process. Finally, students measure the radioactive...
