This short video and interactive assessment activity is designed to teach third graders about subtraction: completing the subtraction sentence.
This is a video and interactive assessment activity designed to help first graders learn about subtraction word problems up to twenty.
This video and accompanying interactive assessment practice was designed to teach Two-step Subtraction (Numbers to 100) - Word Problems to first graders.
This short video and interactive assessment activity is designed to teach second graders an overview of subtraction (numbers up to 10).
This short video and interactive assessment activity is designed to teach second graders about subtracting by counting backward with pictures.
This course features a video review and an assessment practice of subtracting by crossing out with pictures for word problems. It is aimed at first grade math students.
This task provides a familiar context allowing students to visualize multiplication of a fraction by a whole number. This task could form part of a very rich activity which includes studying soda can labels.
The purpose of the first part of this video is to introduce the idea of summation and its notation using the Greek-letter Sigma. We practice working with sums by using Gauss's summation trick. In the second part of the video, we study examples of infinite series, one which converges to a finite number (geometric series), and one which diverges (harmonic series).
In this task students must figure out how much fresh water you must add to get a particular salt concentration in aquarium water.
This is not just for summer! If students are finding Everfi's Hockey Scholar too difficult - this is a great alternative option.
Each summer, students lose critical math and literacy skills, which can widen the achievement gap among students. To prevent this “summer slide,” EVERFI has partnered with Major League Baseball to develop a continuous and engaging learning experience that prepares students of all backgrounds to enter the next school year on track. The 18-week program, targeted to 4th and 5th graders, unlocks activities at regular intervals and offers rewards for progress and consistency along the way. Students engage with content that reinforces critical math and language skills while enjoying the freedom and motivation of a baseball-themed, game-based learning experience.
This Course Covers
Units of Measure
Place Value
Arithmetic
Geometry
Spelling
Phonemic Awareness
Vocabulary
Comprehension
This problem provides students with an opportunity to discover algebraic structure in a geometric context. More specifically, the student will need to divide up the given polygons into triangles and then use the fact that the sum of the angles in each triangle is 180_.
Parts (d) and (e) of this task constitute a very advanced application of the skill of making use of structure: in (d) students are being asked to use the defining property of even and odd functions to manipulate expressions involving function notation. In (e) they are asked to see the structure in the system of two equations involving functions.
The intent of this problem is to have students think about how function addition works on a fundamental level, so formulas have been omitted on purpose.
This short video and interactive assessment activity is designed to teach third graders an overview of addition (sums to 1,000).
This short video and interactive assessment activity is designed to give fourth graders an overview of addition (sums to 1,000).
This short video and interactive assessment activity is designed to teach second graders an overview of addition (sums to 1,000).
This school division developed handbook offers many reading strategies that are applicable for use in the content areas.
Daily lessons and educational activities that kids can do on their own . Topics include reading, writing, science and math, health, language, art, music, fun and games.
We've talked a lot about modeling data and making inferences about it, but today we're going to look towards the future at how machine learning is being used to build models to predict future outcomes. We'll discuss three popular types of supervised machine learning models: Logistic Regression, Linear discriminant Analysis (or LDA) and K Nearest Neighbors (or KNN). For a broader overview of machine learning, check out our episode in Crash Course Computer Science!
An interactive applet and associated web page that demonstrate supplementary angles (two angles that add to 180 degrees.) The applet shows two angles which, while not adjacent, are drawn to strongly suggest visually that they add to a straight angle. Any point defining the angle scan be dragged, and as you do so, the other angle changes to remain supplementary to the one you change. Applet can be enlarged to full screen size for use with a classroom projector.
