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.)
The purpose of this task is to assess ability to interpret the slope and intercept of the least squares regression line in context.
A web page and interactive applet illustrating Thales Theorem (the diameter of a circle always subtends a right angle to any point on the circumference). The applet shows a circle where the user can rotate the diameter and a move a point on the circumference. The applet continuously shows the resulting right triangle, demonstrating that the theorem holds no matter how the points are moved around. Text on the page defines the theorem and relates it to other geometric entities. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.
Simple math test activities for teachers and students, from beginning math operations to calculus. You set the skill level, how many problems, and time limit. A report, which tallies right and wrong answers, is provided after each quiz. Grades: 3–12; cost: Free
Learners will read or listen to a story about two sisters, Marisol and Sofia, as they explore the Sun's role in the water cycle. Additionally, numerous extension resources are included in the accompanying educator guide, such as suggestions for no-cost language arts activities, links to further science activities, a book walk cue chart to guide classroom discussion before, during, and after the story, a graphic organizer, and alignments to the National Science Education Standards (NSES) and the Next Generation Science Standards (NGSS).
This short video and interactive assessment activity is designed to teach third graders about determining unknown angles in composite figures.
Third-grade math instruction is focused on the following areas: developing an understanding of multiplication and division and strategies for multiplication and division within 100; developing an understanding of fractions, especially unit fractions (fractions with numerator 1); developing an understanding of the structure of rectangular arrays and of area; describing and analyzing two-dimensional shapes.
The best way to ensure your students fully grasp the math concepts they'll need to successfully progress in their education is to practice as much as possible. The worksheets, puzzles, games, and other resources available here are the perfect solution for parents and teachers who want to provide their third graders with the tools they need to understand and excel in third-grade math.
Jen Saul combines think time, partner discussions, and an emphasis on students' personal strategies to build confidence through mental math. Students use and discuss the strategies of "decomposing," "splitting," and "jumps of ten."
Families can take math estimation challenges in a wide variety of fun ways.
Game 1: Contig Game: This game challenges and extends the number sense experience students have gained from writing equivalent mathematical expressions for target numbers. Game 2: The 24 Game builds on students' ability to find equivalent names for numbers. Game 3: In Tribulation, students must search the game-board for 3 numbers in a row (vertically, horizontally or diagonally as in a word search) that combine to make the target number. In this game, however, there is a prescribed formula for combining the numbers. Students must multiply the first two numbers then add or subtract the third number to produce the target number.
The purpose of this task is to help students understand composing and decomposing ones, tens, and hundreds. This task is meant to be used in an instructional setting and would only be appropriate to use if students actually have base-ten blocks on hand.
This task allows the students to compare characteristics of two quadratic functions that are each represented differently, one as the graph of a quadratic function and one written out algebraically. Specifically, we are asking the students to determine which function has the greatest maximum and the greatest non-negative root.
This task illustrates A-SSE.1a because it requires students to identify expressions as sums or products and interpret each summand or factor.
Although this task is quite straightforward, it has a couple of aspects designed to encourage students to attend to the structure of the equation and the meaning of the variables in it. It fosters flexibility in seeing the same equation in two different ways, and it requires students to attend to the meaning of the variables in the preamble and extract the values from the descriptions.
This is a simple task about interpreting the graph of a function in terms of the relationship between quantities that it represents.
ile patterns will be familiar with students both from working with geometry tiles and from the many tiles they encounter in the world. Here one of the most important examples of a tiling, with regular hexagons, is studied in detail. This provides students an opportunity to use what they know about the sum of the angles in a triangle and also the sum of angles which make a line.
This task aims at explaining why four regular octagons can be placed around a central square, applying student knowledge of triangles and sums of angles in both triangles and more general polygons.
This short video and interactive assessment activity is designed to give fourth graders an overview of time conversion between words and numbers.
This short video and interactive assessment activity is designed to teach second graders an overview of time patterns.
This short video and interactive assessment activity is designed to teach third graders an overview of time patterns.
This short video and interactive assessment activity is designed to give fourth graders an overview of telling time to quarter and hour.
