Tilted Squares and Right Triangles
Students investigate squares. They generate patterns from structured situations and find a rule for the general term and express it using words and symbols. Students generate patterns from a rule and substitute values and formulas.
Curated OER
Pascal's Triangle
Students study Pascal's triangle. They construct their own version of Pascal's triangle, and relate some of the uses for it. While working through this process, students practice their integer multiplication and division skills.
Curated OER
Patterns in Pascal's Triangle
Students examine the patterns that exist in Pascal's Triangle. They explore multiples and factors. Sudents use an applet to create and color the multiples in Pascal's Triangle.
Curated OER
Finding Patterns in Fractals
Students discover patterns and sequences. They use a website to explore patterns and fractals. Students share their discovery of fractals and their patterns with the class. They develop a list of patterns used in everyday life.
Curated OER
Introduction to Arithmetic and Geometric Sequences
Students examine the concept of sequences. Students create a sequence using varied starting numbers, multipliers, and add on values. Students practice determining the starting values to use in order to produce a desired sequence.
Curated OER
Building Patterns Incrementally
Students study the recurrence rules for patterns where the increase from one term to the next is not constant. They look for the recurrence rule on their own. They copy the pattern and create the next element, continue the pattern with...
Curated OER
Building Patterns Constantly
Students are introduced to some number patterns using buildings constructed with squares. They construct tables of patterns and finding the recurrence rule for a simple pattern where the increase from term to term is a constant.
Curated OER
Box Plots
Young scholars review the concept of median, explore how to calculate quartiles for any size data set and experience how to build a box plot.
Curated OER
Dimensional Space: Various Perspectives
Students use their understanding of 3D on 2D to make a representation of a 4D form on paper.
Curated OER
Tessellations: Geometry and Symmetry
Students examine tesselllations and their geometric properties. They have a better knowledge of polygons, can identify types of symmetry in tessellations. Also students use visulization, spatial reasoning, and geometric modeling to...
Curated OER
From Probability to Combinatorics and Number Theory
Students see how division is used to help solve probability problems. They use tables as data structures where they are used to count outcomes and to compute probabilities. Students use games to help solve probability problems.
Curated OER
Constructing Tangrams
Seventh graders visualize and identify geometric shapes after applying transformations on a coordinate plane. In this tangrams activity, 7th graders construct a set of tangrams and then answer extension questions related to measurement,...
Curated OER
Patterns That Grow
Students investigate growing patterns. In this additive patterns lesson, students analyze the core of growing patterns. Students extend additive patterns based on the core.
Curated OER
Problem Solving in Mathematics
Seventh graders discover that there are multiple strategies to be used in problem solving. They explain a problem solving situation in their own words and determine a possible strategy for solving the problem.
Curated OER
Code Breakers
Students collect data and make a frequency table, change ratios into percents, and analyze data to make predictions.
Curated OER
Make Your Own "Weather" Map
Students create their own "weather" map using data from x-ray sources. They analyze and discuss why it is important to organize data in a fashion in which is easy to read. They compare and contrast different x-ray sources using a stellar...
Curated OER
Calculating Range for a Constant Velocity
Learners read an explanation from the NASA Web-based "textbook", The Beginner's Guide to Aerodynamics, then use the information in combination with data from other Web sites to solve single variable equations for distance (range), time,...
Curated OER
Triangular Numbers
Young scholars are introduced to the problem and brainstorm ideas for approaching the problem and keeping track of what has been done. They work in pairs and share their answers, explaining their reasoning.

Creating Polygons
Students describe, make and compare polygons. In this creating polygons instructional activity, students identify properties of quadrilaterals and describe common features of two dimensional shapes.
Curated OER
Geometry and Symmetry
Students examine tessellations and their geometric properties. The lesson and discussions may be used to develop students' understanding of polygons and symmetry as well as their ability to analyze patterns.
Curated OER
The Farmer's Sheep II
Fourth graders listen to the story of a farmer who only likes to be able to see nine sheet from his window. His wife has brought him another sheep - what now? They work together in pairs to solve the problem and share solutions.
Curated OER
Ohio Census 1990 & 2000
Students use Ohio census data to solve problems, make comparisons, draw conclusions, and support predictions related to Ohio's population. They interpret and work with pictures, numbers and symbolic information.
