This powerpoint starts off by introducing the idea of inferences as we use them in different fields (language arts, media, history, and mathematics). Students use literary skills in ready excerpts of dialogue as they infer as to where the characters are, what they are doing, students also watch commercials (links embedded in slideshow) and use inference skills to answer various questions. Students also consider how historians use inference skills to piece together history by gathering artifacts.

This task has students sort through 8 scenarios matching all equations that accurately represent a particular scenario. I do not tell students this but there is more than one equation to represent all of the 8 scenarios (I typically just tell students that there could be more than one). This activity is a great opener to one-step equations and gets students thinking about how to model scenarios in various way. It also gets students to connect an equation that models a scenario to the equation

This worksheet helps students breakdown quantities of one step equations in order to set up an equation and describe all parts of their equation. Students are also required to justify their equation with pictures and/or written explanation. This could be used as a worksheet/homework or scenarios can be separated and made into stations that students rotate through.

This powerpoint introduces surface area and volume of 3D shapes with a non-circular base. There are also practice problems included to serve as checkpoints in student understanding.

The following task is designed to accompany the minimum wage powerpoint (but can easily be used without it). This project is designed for students to understand how we can connect mathematics real world issues and how to discuss these issues through a mathematical lens.

This packet is an introduction to solutions to systems of equations by graphing, tables, and equations. Scenarios are provided as well as scaffolding questions to help guide student thinking. This lesson is also meant to build students towards understanding that to determine when two linear systems will meet we can set the two linear expressions equal to one another and solve for x.

This powerpoint shows students the importance of organizing data. It also nicely lays out step by step instructions as to how a boxplot is constructed. This allows for students to take notes that will be beneficial to refer to later. This powerpoint then gets into students interpreting/making sense of box plots based on the 5 measures of center provided.

This power point serves to develop a conceptual understanding of solving a system of two equations using substitution. Starting with word problems allows students to have a concrete reference for an abstract concept. The power point also includes some extra word problems to solve as a whole class, small groups, or individually. There are extension problems towards the end dealing with speed, distance, and when two moving vehicles will meet.

This worksheet is great for introducing the idea of surface area. It asks students to breakdown various 3d shapes into the 2D shapes they are made of and, by using those area formulas that students should already be familiar with, allows them to better conceptualize the formula for 3D shape surface areas.

This worksheet uses the idea of snapchat as a way for students to understand groups of more than one quantity.

This powerpoint serves as an introduction in multiplying positive and negative numbers. It builds off students' existing understanding of additively combining positive and negative numbers and serves to develop conceptual understanding as to WHY a positive x a negative integer is always negative. ** See also my FREE resource about combining positive and negative integers-- they flow nicely together.

This powerpoint is meant to be used in addition to my inequalities worksheet. This powerpoint serves as the intro to the topic of minimum wage (what is it? did we always have it? why might we need it?).

This powerpoint serves to develop conceptual understanding of why we need a common denominator when adding or subtracting fractions. It allows students to discover what multiplying a numerator and denominator of a fraction looks like and why doing so makes sense.

This opener to two step equations has students think about balancing scales first with non-numerical objects (in this case shapes). They will connect their process to determining the weight of one shape in terms of another shape to the algebraic process of solving for an equation. The last few slides transition students from working with weight of shapes to a standard two-step problem wherein they are expected to identify the meaning of each term in a set of equivalent expression. The point of t

This powerpoint includes an introduction to naming circles and identifying a circle's radius and diameter. It also takes a more conceptual approach to introducing the circumference formula. Practice questions are included but supplemental practice should be provided.

This powerpoint introduced the distributive property as it ties to our existing understanding of multiplication as being groups of a certain amount whereas the distributive property is groups of multiple quantities instead of just one.. ** See my multiplication powerpoint**

This website provides an opportunity for students to develop a conceptual understanding of the area formula for a circle. The teacher should provide supplemental practice (although there is some practice provided in the powerpoint). This powerpoint also provides the extension of students determining the area of a shaded region.

This powerpoint introduces complementary, supplementary, adjacent, and vertical angle relationships. There are also whole-class practice problems.

This worksheet helps students develop a conceptual understanding of the standard method of inverse operations when solve one, two, and multi step equations. This worksheet mainly deals with equations including fraction coefficients. Please look for my other worksheets that use the same format with standard two-step equations and equations involving the distributive propoerty.

This worksheet nicely accompanies my One step with fractions powerpoint (but can be used without it as well). This worksheet allows students to understand why we multiply each side of an equation by the reciprocal of a fraction-coefficient in order to solve for a variable.
