Weights
Students find an object that they estimate weighs 20g and check estimates on the balance scales. They read the problem and work in pairs focusing their understanding on the size of grams.
Curated OER
Easy Estimation
Students use estimation as a math strategy. Students estimate the number of small snacks that are presented to them. Students count the snack items after they have estimated how many there are, before the class snack on a daily basis.

Measurement: Lesson 2
Eighth graders complete math problems given in this lesson plan, where they find the perimeter and area of specific figures. They estimate the perimeter and area of shapes and figures and then complete the mathematical formula to find...
Curated OER
River Width
Students determine the level of accuracy needed for computations involving measurements and irrational numbers. They use the correct number of digits in computation to achieve an appropriate unit or level of accuracy when solving...
Curated OER
Marshmallows
Third graders estimate the volume and mass of one marshmallow using appropriate standard units. They design and carry out an investigation to find the average of volume/mass of one marshmallow.
Curated OER
Measurement
Students use arithmetic in a practical situation using time and distance.
As the calculations involved in this problem involve single digit addition and multiplication it offers a good opportunity to encourage the students's use of...
Curated OER
Locating the Salt Front
Students use Hudson River salinity data to create a line
graph that shows the location of the salt front, and use math
skills to explore how this location varies over time. They use the graph to estimate the location of the salt front...
Curated OER
Conversions That Make Cents
Eighth graders practice calculating problems using addition, subtraction, multiplication and division. They estimate solutions to algebraic problems. They also graph their solutions.
Curated OER
Scavenger Hunt
Second graders participate in a Scavenger Hunt to find out how long 1 cm is. They then find 10 objects that estimate to be 1 cm in length and record their findings on the table provided and check their estimates using a ruler.
Curated OER
The Basketball Tournament
Students estimate how many games are played if six teams play each other once. They investigate their own way and discuss possible strategies they might use. They then share their findings with the class.
Curated OER
The Part-adder 1
Second graders investigate the addition of whole numbers. They mentally perform calculations involving addition and subtraction. They make sensible estimates and check the reasonableness of answers.
Curated OER
Charting Attendance Rate of Busch Gardens
Sixth graders, in groups, are given different parts of the whole project. They use information from Busch Gardens to explore line graphs, averages, and other math vocabulary.
Curated OER
Practicing Arithmetic
High schoolers practice single operation arithmetic ranging from single digit addition to long division of decimals or real numbers using Graphit. They use data sets and rules to graph ordered pairs.
Curated OER
Spheres
High schoolers work algebraic expressions with various types of powers to find the solutions. They Students also become familiar with problems that involve the square roots of numbers. The work should be completed with computational...
Curated OER
Particulate Sampler
Students estimate the extent of particulate air pollution present in their neighborhoods.
Curated OER
Paper Capers
Young scholars demonstrate how much paper is thrown away in their classroom in one week. They estimate the weight of paper used, weigh the paper at the end of five days, and discuss how students can use less paper.
Curated OER
Buying My First Car
Students pretend they are about to buy their first new car. They must do all the calculations necessary to estimate the cost of purchasing the car. They see that the math they learn in school really does have real-life applications.
