This video module presents an introduction to cryptography - the method of sending messages in such a way that only the intended recipients can understand them. In this very interactive lesson, students will build three different devices for cryptography and will learn how to encrypt and decrypt messages. There are no prerequisites for this lesson, and it has intentionally been designed in a way that can be adapted to many audiences. It is fully appropriate in a high school level math or computer science class where the teacher can use it to motivate probability/statistics or programming exercises. nteractive lesson, students will learn to build the cryptography devices and will learn how to send and ''crack'' secret messages.

This is an integrated lesson which is introduced using the book "The Very Hungry Caterpillar" by Eric Carle. Butterfly metamorphosis is explored through art, math, and writing.

This is a remix of Color Week from Illustrative Mathematics, https://tasks.illustrativemathematics.org/content-standards/tasks/1110.   The purpose of this activity is to give students practice in collecting data and answering questions related to the gathered data that is displayed in a picture graph to support sol K.11a and K.11b.  Students wear a different color shirt each week to represent the color of the week, collect the data by coloring a shirt, place it on the graph, and count how many were worn of that color. 

In this lesson, students will use manipulatives to prove that when comparing fractions, the larger the denominator the larger the piece.  Also, when pieces are the same size (the denominator), the numerator denotes how many pieces of that size we have.

In this lesson, students will use manipulatives to prove that when comparing fractions, the larger the denominator the larger the piece.  Also, when pieces are the same size (the denominator), the numerator denotes how many pieces of that size.  Students will be able to sort fractions quickly by adding the fraction by itself to determine if it is smaller, equal, or larger than ½. 

This Desmos activity has students partiiton a fraction into fourths, model a fraction, and then determine if the fraction is more than, less than, or equal to 1/2 by looking at the denominator.

This video is part of the Learn and Grow with WHRO TV series. Watch Brandon Thompson teach about repeating patterns.

This resource will show how to teach your students to make their own "formula calculator" using Java programming, and it has handouts for your students or your own use. It is ideal for Grade 7 and Grade 8 Math.The video in this resource walks you through the steps to teach your students to program their "formula calculator" using Java programming after they have been taught about geometric formulas. They can then use their calculator to help them solve their math problems. It will reinforce critical thinking skills and create a deeper understanding of how the formulas work.Students can use any Java IDE or even an online IDE. The lesson can be customized based on your familiarity with Java and your students' computer skills.The handouts show how to use arithmetic operators in Java as well as some Math class methods that will be helpful. The attached program can be used as a starting point for their programs. 

With your mouse, drag data points and their error bars, and watch the best-fit polynomial curve update instantly. You choose the type of fit: linear, quadratic, cubic, or quartic. The reduced chi-square statistic shows you when the fit is good. Or you can try to find the best fit by manually adjusting fit parameters.

This PowerPoint reviews fractions as parts of a whole, powers of ten, and introduces decimal place value.  Students will use money to find equivalent fractions and decimals.

Mic Drop Maths is a mathematics podcast for 5th graders based on the VA Standards of Learning. Each episode addresses one standard and is broken into segments including concept, real-world application, math history, literature connections, misconceptions, and more! There is music, sound effects, jokes, and student voice in each engaging and entertaining episode. 

This video is part of the Learn and Grow with WHRO TV series. Watch Shantel Davis teach addition and subtraction strategies.

The student will create & solve single-step story and picture problems using addition and subtraction

Learn about graphing polynomials. The shape of the curve changes as the constants are adjusted. View the curves for the individual terms (e.g. y=bx ) to see how they add to generate the polynomial curve.

 I created the Equations True or False Jamboard to give my students practice with identifying equations.  They used a graphic organizer to solve each equation and then sorted it to the true or false column.  You could also have students work the problems on whiteboards.  Before doing the sort, we practiced finding the answers to equations and creating equations that were true.  We talked about the equal and not equal sign and how that might change whether or not an equation is true or false.  This activity supports sol 3.17.   

 I created this partner game to give my students practice estimating sums and differences.  This game supports sol 3.3a, estimate and determine the sum or difference of two whole numbers.  Before playing the game, students should have already studied rounding.    In this game, students take turns flipping over four cards and rounding the number.  Then, they add the rounded numbers to find the sum or subtract the rounded numbers to find the difference.
