Curated OER
V-Numbers
Students explore problem solving strategies. Gin a novel situation, students develop a mathematical theory. Through models and mathematics, students justify their solution. Students definea V-sets and discuss conjectures about each set.

Brian's Pegboard II
Learners are able to assess a problem and use systematic methods to solve the problem. They also find out all the possible outcomes for a sequence of events using tree diagrams.
Curated OER
Bubblegum balls
Young scholars look for patterns to solve problems involving statistics using different colored gumballs. They should be able to look for and find out all the possible outcomes based upon inference and trials.
Curated OER
Penny's Box
Students need to be able to calculate the volume and surface area of a cuboid as well as present a systematic list of results in order to justify the minimum case. The use of three factors of 100 is also important.
Curated OER
Bill's Badge
Students explore the making of circles and concepts related to them in geometry. The project is inquiry based will focus upon students making their own nametags. The construction is ideal for hands on students.
Curated OER
Karen's Tiles
Students investigate how perimeter changes as area changes to see the relation between area and perimeter for similar shapes. They then students answer the question if the area of the rectangle increase, does its perimeter have to increase?

Jackson's Consecutive Numbers
Students generate patterns from a structured problem, finding a rule for the general term, and expresses it in words and symbols. They then devise and use problem solving strategies to explore situations mathematically.
Curated OER
Can Stack
Students are able to find the rule for summing consecutive numbers;
identify the pattern of triangular numbers. They then solve the given problem using logic and mathematical reasoning.
Curated OER
Spheres
Young scholars 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
Rows of Numbers
Students generate patterns from a structured situation, find a rule for the general term, and express it in words and symbols. They also devise and use problem solving strategies in a systematic way.
Curated OER
Base 3
Students investigate this problem that aims to give a better idea of our decimal system by looking at a comparable system - the base 3 system. By seeing how base 3 numbers work students should have a better appreciation of base 10...
Curated OER
Time Problems
Students make sensible estimates and check for reasonable results. They also solve problems with positive and negative integers using practical activities or models as needed.
Curated OER
Square and Triangular Numbers
High schoolers use equations to represent practical situations. They solve linear equations and quadratic equations. The use of problem solving strategies is also developed.
Curated OER
Adding Ten Tiles I
Students practice this problem that needs a certain amount of experimentation (trial and error) to get any answer at all. In the process they practice their basic number facts. However, to get the complete set of answers Students need to...
Curated OER
From a Square to a Rectangle
Eighth graders solve problems involving percentage increases and decreases. Using given percentages, 8th graders transform a square into a rectangle. They apply the area formulas for squares and rectangles.Students observe the percent...
Curated OER
No-Three-In-A-Line Again
Students interpret information and results in context while using words and symbols to generalize patterns. They use symmetry and angle properties of polygons to solve practical problems and identifying invariant properties under...
Curated OER
Richard's Dice
Students problem solve logic problems. They complete a worksheet using dice as a manipulative. They decide on a problem solving strategy, solve the problem, and write up the solution.
Curated OER
Space Crossing
Students critically follow a chain of reasoning to devise a decent problem solving technique to be applied to a reasonable problem. They also examine how to use logical arguments.
Curated OER
4c and 7c Stamps
Fifth graders determine what it takes for a sequence of numbers to carry on infinitely. They examine patterns that can be made using linear combinations of 4 and 7 based on the use of four cent and seven cent stamps. They use appropriate...
Curated OER
Poppy Meets Pythagoras
Eighth graders find connections between numbers in a table; use Pythagoras' theorem in a general algebraic form; and measure accurately from a scale drawing to find a method that might enable the helicopter to land inside a rectangular...
Curated OER
Rings and Diamonds
Fifth graders solve a problem by using systematic problem solving strategies. They determine if there is enough information to solve the problem. They solve a problem involving geometric shapes and area.
Curated OER
My Son is Naughty
Pupils find factors of numbers; work systematically; and use logic to explain away certain possible number combinations. They then devise and use problem solving strategies to explore situations mathematically.
Curated OER
Make the Highest Total
Sixth graders predict the outcome of a simple probability experiment, test it and explain the result by using problem solving strategies to explore situations mathematically. They then play a few games informally where students play in...
