In this new 15 episode Learning Playlist, James Tanton will guide us through solving equations and understanding how math works with our very human brains.
Students create exponential models to predict the speed of video game processors over time, compare their predictions to observed speeds, and consider the consequences as digital simulations become increasingly lifelike.
Students use proportional reasoning to determine how far a car travels in the time it takes to text.
In this lesson, students examine some other ways to keep track of dates, and use number sense and function concepts to convert among different calendars.
In this lesson, students create polynomial functions to model the expected value of a given bid and determine the optimal amount someone should bid in any auction.
This 4-week curriculum unit we have developed is one that can be used to introduce algebraic concepts at any grade level.
This lesson presents two classic problems (Mangoes ProblemĀ andĀ Sailors and Coconuts) that can be represented and solved in several different ways.
To test their conjectures, students gather data using one of three different methods: using a simulated online dive; covering a tank with plexiglass to simulate ocean water; or, incrementally filling a column with water to simulate increasing depth.
Both ends of a small chain will be attached to a board with a grid on it to (roughly) form a parabola.
Crosses can be drawn on number grids of various sizes. What do you notice when you add opposite ends?
Can you explain the surprising results Jo found when she calculated the difference between square numbers?
Can you put these products in order of size?
