Areas of Regular Polygons and Circles
Learners explore area of polygons and regular polygons in this math lesson. They calculate the area of several polygons using Cabri Jr. and analyze shapes and write formulas to solve for the area.
Curated OER
Distributive Property
Learners solve problems using distribution. In this algebra lesson, students factor equations using the distributive property. They graph their solution on a graph.
Curated OER
Using Tables to Solve Linear Functions
Oh that intercept! Budding algebra masters solve linear equations from standard to intercept form. They identify the slope and y-intercept to help graph the lines, an then create coordinate pairs using a table of values. Great TI tips...
Curated OER
Triangle Midsegment
Learn how to calculate the length and midsegments of triangles. Learners differentiate between similar and congruent triangles. They create a spreadsheet with their findings.
Curated OER
Quadratic Functions and Stopping Distance
Learners solve quadratic equations. In this algebra lesson, students factor and graph quadratic functions. they use the properties of quadratics to calculate the distance.
Curated OER
Landscapes
Students explore landforms and landscapes. They demonstrate an appreciation for and examine how to recognize the attributes of landforms and landscapes. Students create a landscape and reflect on their painting.
Curated OER
Solving Systems by the Elimination Method
Pupils solve equations by elimination and use the TI to graph the lines and find the point of intersection.
Curated OER
Introduction to Correlations
Learners investigate correlations between human body height and other human features. They select ten subjects and record each subject's age and gender and measure for height, wingspan, distance, and size of hands. After measuring, they...
Curated OER
Simplifying Equations of the Form ax+b=cx+d
Students solve equations of the form ax+b=cx+d and visualize the concept of "balancing" an equation.
Curated OER
Let it Grow, Let it Grow, Let it Grow
Students investigate, through a hands-on activity, in which type of soil a bean seed grows best. They create a bar graph representing each plant's growth in different soils.
Curated OER
Downhill Discoveries
Students are involved in hands-on activities to determine how course conditions affect bobsled, luge, and downhill ski races.
Curated OER
Composting
Eighth graders collect data from Bottle Biology compost columns and record using Excel spreadsheet.
Curated OER
Chilly Discoveries
First graders make ice cream and determine what makes this liquid turn into a solid.
