Pupils develop techniques for estimating the area of a circle and use ideas about area and perimeter to solve practical problems. For this area and perimeter lesson, students apply the concepts of perimeter and area to the solution of...

Students explore the concept of area under a curve. In this area under a curve lesson, students find the area under a curve using the Monte Carlo method using random points and probability. Students calculate the area under the same...

Fourth graders estimate the surface area of a pond using the chance method and the estimation method. They complete a graph and a short report comparing the results of the two methods.

Students examine the painting "Old Man With A Gold Chain" by Rembrandt. They identify geometric shapes in the painting, measure these shapes and compare the relationships of these measurements.

Students identify the equation to represent a circle. In this algebra lesson, students review properties of conics and how they are related. they use a robot to create a visual of circles and their application to the real world.

Students identify diagrams of quadrilaterals and circles by different names and classify the figures. They name the areas for each diagram and practice solving the formulas for each.

Students solve the area for parallelograms,squares, rectangles, trapezoids, and triangles. In this geometry lesson, students compare and contrast two dimensional shapes and apply their properties to solving real life scenarios. This is a...

Third graders examine the main parts of a bar graph and how to round up to the nearest tenth. They make an example of a bar graph and answer questions based on the graph using a list of state capitals and their average temperatures....

Students determine an efficient layout of the pattern pieces needed to make a sports bag with given dimensions and specifications. Given a word problem, data set and a diagram, students evaluate the information they have available and...

Students make a sundial. In this time lesson, students determine the time of the day by creating a sundial. They check the time on the sundial, hourly, for one week. Afterward, they explore what happened to the shadows in reference to...

Simulate a random sampling of data by tearing 20 sheets of paper into slips and place a number on 10 and a letter on 10. They place the slips in two separate containers and randomly draw a number and a letter. They record their...

Students create an Excel spreadsheet of a personal budget by estimating their possible income and monthly expenses from a worksheet. They group together to create a family unit and use the personal budget sheets to plan a family budget.

Students measure and convert between units. In this geometry lesson, students investigate through measurements of distances. They relate the properties of circle to solving problems with radius, diameter and area.

Students duplicate the method that Archimedes used to estimate the value of pi. They complete a data table and find the approximate values of pi for three sets of polygons.

Third graders describe an amount of turn from a particular position to another using the 'circular' benchmarks of 0, ++, ++, ++, and full turn. Estimation language such as 'just about', 'between', 'not quite', 'just over', and similar...

Students collect sunflower heads from their community garden. They estimate its seed count using different strategies. They graph their estimations on a graph and use calculators to find the actual total.
