This is a general collection of math resources. It is a large collection, but you can use the fliters on the left side of the screen to filter down to the specific education level you are looking for. (You are encouraged to filter by education level, not grade.)
This is an instructional task related to deepening place-value concepts. The important piece of knowledge upon which students need to draw is that 10 tens is 1 hundred.
This short video and interactive assessment activity is designed to teach third graders about counting vertices and sides in various shapes.
The objective of this lesson is to gain automaticity counting to 100 and to establish the importance of multiples of ten. The final goal of this lesson is for students to be able to count by tens and articulate the term for this.
Ten printable colouring pages which depict the numbers one through ten. Each page has a spelled-out number in Michif, the language of Métis Peoples’, as well as the numerical equivalence. There are also images of culturally significant items on each page, which correspond with the respective number. There are written instructions on the bottom of each page that indicate different activities that supplement the colouring pages.
This task involves solving equations with rational coefficients, and requires students to use the distributive law ("combine like terms"). The equation also provides opportunities for students to observe structure in the equation to find a quicker solution, as in the second solution presented.
This task presents a real world application of finite geometric series. The context can lead into several interesting follow-up questions and projects. Many drugs only become effective after the amount in the body builds up to a certain level. This can be modeled very well with geometric series.
Welcome to Crash Course Statistics! In this series we're going to take a closer look at how statistics play a significant role in our everyday lives. Now this a "math" course, and there will definitely be some math, but we're going to focus on how statistics is useful and valuable to you - someone that performs AND consumes statistics all the time. Statistics are everywhere from batting averages and insurance rates to weather forecasting and smart assistants, and it's our hope that when you finish this series you'll get a better idea of the role statistics play in helping us better understand the world!
Graphs and charts are great because they communicate information visually. For this reason, graphs are often used in newspapers, magazines and businesses around the world.
NCES constantly uses graphs and charts in our publications and on the web. Sometimes, complicated information is difficult to understand and needs an illustration. Graphs or charts can help impress people by getting your point across quickly and visually.
Here you will find five different graphs and charts for you to consider.
Create a graph using this site.
This short video and interactive assessment activity is designed to teach fourth graders about creating largest and smallest numbers given digits.
My goal was to bring 21st Century Competences with the focus of critical thinking into my Gr. 2 Math classroom. I show a droodle – an abstract drawing. I ask students to take a few moments and think about what it could be. Then they can discuss with a partner, and finally share what they thought. Afterwards we have a discussion around “right” and “wrong” answers – which is a common way to think around math. No one is wrong – these are all good ideas that could answer the question: What could this be?
In this example, students learn how to read a topographic map and understand map contours. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.
Students practice crossing from one family to the next in counting forward with this concentration game.
This word problem requires students to create expressions to calculate gas milage for a vehicle.
This site offers kids to fun opportunity to crack ciphers, discover secrets, and improve their math skills!
An interactive applet and associated web page that demonstrate the properties of a cube. A 3-D cube is shown in the applet which can be interactively manipulated using the mouse. Research has shown that some younger students have difficulty visualizing the parts of a 3D object that are hidden. To help with this, the student can rotate the cube in any axis simply by dragging it with the mouse. It can also be 'exploded' - where a slider gradually separates the faces to reveal the ones behind. The cube can also be made translucent so you see through it to the other side. Applet can be enlarged to full screen size for use with a classroom projector, and printed to make handouts. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.
An interactive applet that allows the user to graphically explore the properties of a cubic equation. Specifically, it is designed to foster an intuitive understanding of the effects of changing the 4 coefficients in the function. The applet shows a large graph of a quadratic (ax^3 + bx^2 +cx + d) and has four slider controls, one each for the coefficients a,b,c and d. As the sliders are moved, the graph is redrawn in real time illustrating the effects of these variations. Applet can be enlarged to full screen size for use with a classroom projector.

One common mistake students make when dividing fractions using visuals is the confusion between remainder and the fractional part of a mixed number answer.
This task requires students to computer currency exchanges.
