A Visual Arts Activity Inspired by Works of Art from the VMFA Collection

Cultures all over the world create decorative patterns, perhaps inspired by the enduring patterns humans see in the natural world that surrounds us, from the cycle of the seasons to the pattern of the stars in the heavens. These hands-on activities, which can be adapted for a number of grade and ability levels, introduce repeating and alternating patterns, as well as the concept of a visual motif.

This simulation allows you to use a slider to see how positive and negative integers add on a number line.

The goal of this activity is to solidify students' understanding of functions: Input/Independent Variable/Domain → Output/Dependent Variable/Range in math and relate that to functions in CS.

This learning video introduces students to the world of Fractal Geometry through the use of difference equations. As a prerequisite to this lesson, students would need two years of high school algebra (comfort with single variable equations) and motivation to learn basic complex arithmetic. Ms. Zager has included a complete introductory tutorial on complex arithmetic with homework assignments downloadable here. Also downloadable are some supplemental challenge problems. Time required to complete the core lesson is approximately one hour, and materials needed include a blackboard/whiteboard as well as space for students to work in small groups. During the in-class portions of this interactive lesson, students will brainstorm on the outcome of the chaos game and practice calculating trajectories of different equations.

The first skill I practice with my students on area is counting the square units inside of a regular shape.  It gives them a better understanding about area.  This activity supports sol 3.8b, counting the number of square units needed to cover a given surface in order to determine its area.  I created this jamboard for my virtual students, so that they are doing the same lesson as my in person students and I can see their work in real time.  Jamboard has been an essential Google tool for me during this school year while teaching both in person and virtual students.

I created this game to use in a place value lesson.  This activity supports sol 3.1a, read, write, and identify the value of each digit in a six-digit whole number, with and without models.  Before this lesson, my students identified digits, placement of commas to form large numbers, and read numbers written in standard form. The focus of this lesson is to read numbers written in standard form and word form.  The teacher gives the students a card with a standard form or word form number.  They travel the room to find their partner.  Then, students tell the class how they know they are partners.  Student talk is incorporated into the lesson.  This is vital and allows students to develop thoughts and convey ideas about what they are learning.

This learning video presents an introduction to the Flaws of Averages using three exciting examples: the ''crossing of the river'' example, the ''cookie'' example, and the ''dance class'' example. Averages are often worthwhile representations of a set of data by a single descriptive number. The objective of this module, however, is to simply point out a few pitfalls that could arise if one is not attentive to details when calculating and interpreting averages. The essential prerequisite knowledge for this video lesson is the ability to calculate an average from a set of numbers. During this video lesson, students will learn about three flaws of averages: (1) The average is not always a good description of the actual situation, (2) The function of the average is not always the same as the average of the function, and (3) The average depends on your perspective. To convey these concepts, the students are presented with the three real world examples mentioned above.

 I created this game to give my students hands on practice with counting money.  Counting money is a skill that is used daily in real life, so it is necessary that all students master the skill.  This activity supports sol 3.6a, determine the value of a collection of bills and coins whose total value is $5.00 or less.  Before playing this game, students should be able to recognize coins and know the values of each.  This game has four recording sheets so you can differentiate instruction based on the needs of your students.  Students play with a partner to flip cards, write the number under each column, and put dollars/coins on the work mat to count.  While students play the game, I walk around to help students as needed.  By doing this, I can assess and remediate with those students who need extra help.
