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.)
Students are asked to analyze the data in a graph and determine if there is an association between the two variables.
The triangle congruence criteria, SSS, SAS, ASA, all require three pieces of information. It is interesting, however, that not all three pieces of information about sides and angles are sufficient to determine a triangle up to congruence. In this problem, we considered SSA. Also insufficient is AAA, which determines a triangle up to similarity. Unlike SSA, AAS is sufficient because two pairs of congruent angles force the third pair of angles to also be congruent.
In our series finale, we're going to take a look at some of the times we've used statistics to gaze into our crystal ball, and actually got it right! We'll talk about how stores know what we want to buy (which can sometimes be a good thing), how baseball was changed forever when Paul DePodesta created a record-winning Oakland A's baseball team, and how statistics keeps us safe with the incredible strides we've made in weather forecasting. Statistics are everywhere, and even if you don't remember all the formulae and graphs we've thrown at you in this series, we hope you take with you a better appreciation of the many ways statistics impacts your life, and hopefully we've given your a more math-y perspective on how the world works. Thanks so much for watching DFTBAQ!
This activity lets students measure distances in the classroom using parallax. The exercise can be done either at a high school level using trigonometric functions, or at a middle school level using simple arithmetic approximations to the trigonometric functions. A work sheet is provided for the middle-school-level activity.The 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 will be exploring the 100's Chart by finding different emojis and recording them on their recording page. There are three different game board to allow for lots of practice. This game is best set up as a math rotations/center.
This short video and interactive assessment activity is designed to teach second graders about which amount is not equal to a given amount of money?.
This task addresses knowledge related to interpreting forms of functions derived by factoring or completing the square. It requires students to pay special attention to the information provided by the way the equation is represented as well as the sign of the leading coefficient, which is not written out explicitly, and then to connect this information to the important features of the graph.
The purpose of this task is for students to explain how they know one quantity is greater or less than another quantity. Students will easily be able to identify which number is greater or less. However, explaining their reasoning will help them solidify their number sense skills.
Math puzzles to get students talking about their mathematical thinking. The site provides a collection of shape, number and graph sets. Each activity has four images/numbers, students then need to pick which one doesn't belong. But the trick is this, the puzzles do not have one correct answer. This can lead to interesting conversation and descriptions of what the student notices about the arrangement.
If you think up your own, you can submit them to the site.
In this task students see different ways of partitioning a circle and a rectangle into two or more equal shares.
In this task students compare 4/5 to 5/4 on a number line.
In this activity students compare objects and practice determining which objects are heavier and lighter.
This is a lesson about the distribution of dust in the solar system. Learners will use data from the Student Dust Counter (SDC) Data Viewer to establish any trends in the distribution of dust. Students record the number of dust particles, or hits, recorded by the instrument and the average mass of the particles in a given region.
White Rose Math is a teacher group which offers math training and resources, including lesson plans and ideas. The resources on the site are meant for parents and teachers. The content is organized by grade level based on the British system. The White Rose Maths Team has prepared a series of maths lessons for each year group from Year 1-8. Every lesson comes with an answer key and a short video showing the teacher or parent clearly and simply how to help the child to complete the activity successfully.
For students K-8.
Once students have developed conceptual understanding of the basic operations they need to develop fluency with the facts. One quick way to include daily practice and motivate students to master these basic facts is through the use of the Who Has? card decks. These decks can be created for virtually any topic and frequent use as both a whole class practice or as a center activity for partners or small groups will provide facts practice in a highly-motivating format.
In this real world word problem students must graph linear equations.
A great place to come for math ideas and embracing a love of math.
The two triangles in this problem share a side so that only one rigid transformation is required to exhibit the congruence between them. In general more transformations are required and the "Why does SSS work?'' and "Why does SAS work?'' problems show how this works.
For these particular triangles, three reflections were necessary to express how to move from ABC to DEF. Sometimes, however, one reflection or two reflections will suffice. Since any rigid motion will take triangle ABC to a congruent triangle DEF, this shows the remarkable fact that any rigid motion of the plane can be expressed as one reflection, a composition of two reflections, or a composition of three reflections.
This particular sequence of transformations which exhibits a congruency between triangles ABC and DEF used one translation, one rotation, and one reflection. There are many other ways in which to exhibit the congruency and students and teachers are encouraged to explore the different possibilities.
