  • Subtracting Integers on Google Slides

    This post shows the use of Google Slides to develop the concept of subtracting integers. Google Slides can be accessed here. Make a copy to use and edit it.


  • Adding Integers with +- Counters on Google Slides

    This post shows the use of Integers counters on a Google Slides document. Here is a link to a FREE copy of the Google Slides.


  • Intro to Concept of Functions

    Intro to Concept of Functions

    Functions are perhaps the most prevalent and important topic covered in secondary math, aside from maybe 1 variable linear equations. The concept of a mathematical function is challenging for many students. This post provides details about a meaning making approach to introducing functions. Overview The introduction is presented on a Google Jamboard, to allow for…


  • Intro to Percent Change on Jamboard

    Intro to Percent Change on Jamboard

    This post provides details about an artifact that has a manipulative and visual representation of tax rate and discount rate. These contexts are used as an introduction to percent change. The manipulatives are presented on a Google Jamboard. Overview The price or original price is presented as dollar bill. The bill is cut into proportional…


  • Intro to Graphing Linear Functions using Jamboard

    Intro to Graphing Linear Functions using Jamboard

    Graphing linear functions may be the most important topic in Algebra 1. While proportional reasoning is a prelude to functions, this is the first formally identified function presented to them. The graphing leads to slope and intercepts, beyond the entry point for graphical representations to functions. This post presents an activity that can serve as…


  • Subtraction within 10 – Jamboard

    Subtraction within 10 – Jamboard

    This post presents a Google Jamboard manipulative activity to help scaffold the act of subtraction which helps unpack the concept of subtraction. Overview The Jamboard can be individualized with Google Images. The can allow for context. In this example, maybe the context is there are 7 players and 4 have an injury or on COVID…


  • Exponent Rules with Jamboard

    Exponent Rules with Jamboard

    The Product and Quotient Rules are challenging largely because there are few ways to present them in an accessible format. This post outlines an approach using manipulatives on a Google Jamboard. Jamboard The Jamboard activity involves using moveable variables as manipulatives to provide a hands on approach to learning the rules. The first slide presents…


  • Introduction to Adding Integers

    Introduction to Adding Integers

    Operations on integers and integers in general is challenging for many students. Negative numbers are abstract. Whole numbers and fractions can be represented with images. The activity presented draws upon student prior knowledge of thumbs up and down in a vote to make negative more accessible. The following images are from a Jamboard. Here are…


  • Introduction to Volume – Manipulatives (starting with perimeter and area)

    Introduction to Volume – Manipulatives (starting with perimeter and area)

    Here is a Jamboard to introduce volume and units of volume. (See photo at very bottom for making a copy to edit.) The students start with building an animal pen and shading in the space inside. The hands on approach and connection to prior knowledge of a fenced in area for animals sets the stage…


  • Combining Like Terms – From Concrete to Symbolic Form

    Combining Like Terms – From Concrete to Symbolic Form

    Here is a Jamboard (see photo at very bottom for how to make a copy to edit) that presents like terms as visual manipulatives and then eases into the symbolic form – the “mathy” stuff. The following shows each slide as is and how it looks after completion. Start with two groups of common items,…
