This additional 6-problem assessment can be used as a quiz to cover 6th grade Common Core standard: CCSS.Math.Content.6.NS.B.4 which covers GCF, LCM, and the distributive property. This assessment has the same format of problems as Assessment #1, but different numbers and word problem scenarios. There are two problems in each category. For LCM there is one problem to find the LCM of two numbers and one word problem in which you need to determine that finding the LCM will solve the problem. For G

This 23-slide PowerPoint presentation is recommended as useful instruction before learning to calculate distance between points in a coordinate plane (CCSS.MATH.CONTENT.6.NS.C.8). It is meant for students who have already learned about absolute value, but have not learned about basic operations involving negative numbers yet (i.e. addition/subtraction). Students will learn how to calculate the distance between any two points on a number line using their absolute values. They will see that this s

This original 6-problem assessment can be used as a quiz to cover 6th grade Common Core standard: CCSS.Math.Content.6.NS.B.4 which covers GCF, LCM, and the distributive property.

This 22-slide PowerPoint presentation demonstrates how to use common factors and the distributive property to change an expression. Addition problems involving whole numbers are changed into a multiplication problem which is the product of the greatest common factor of the addends and the sum of two whole numbers that have no GCF other than "1". The content is based on 6th grade Common Core standard: CCSS.Math.Content.6.NS.B.4. The presentation takes about 30 minutes, but time considerations dep

This 18-slide PowerPoint presentation uses word problems to explore the role of multiples in solving them. It begins with defining a multiple before being introduced to problems involving common multiples. In the first problem you're looking for several common multiples over a period of time. The second problem is looking for the next time an events occur simultaneously (LCM). After summarization there is a problem students can work along with solution so they can check their work. The presentat

This 18-slide PowerPoint presentation goes deeper into understanding absolute value. It demonstrates the difference between comparing two numbers and comparing the absolute value of two numbers. Real-world examples are given to help students better understand the material. Completely review the presentation so you can decide how best to use it in your curriculum. The content is based on Common Core standard CCSS.Math.Content.6.NS.C.7.D. The instruction assumes that the student has already experi

This 18-slide PowerPoint presentation introduces students to the concept of absolute value. Material is presented that would satisfy Common Core standard CCSS.Math.Content.6.NS.C.7.C. The definition of absolute value is based on the distance from the number to zero on a number line. Magnitude is defined and discussed in detail. Simulation, examples, and practice are incorporated. The presentation can be used for full class participation or individual use. It's great for use on student accessible

This 16-slide PowerPoint presentation uses a three-step process to compare different numbers. Writing a statement of inequality using the numbers an correct inequality symbol is the 1st step. Explaining in words what the statement of inequality means is the 2nd step. The 3rd step is to interpret the relative position of each number on a number line (both horizontal & vertical number lines are used). Positive & negative numbers are both used in examples. Those viewing this presentation have alrea

This 20-slide PowerPoint presentation tests and develops three rules involving reflections resulting from sign changes in an ordered pair. The three rules involve changing the x-coordinate sign only, changing the y-coordinate sign only, and changing both coordinate's signs. Thus the result is reflection across the y-axis, reflection across the x-axis, and reflection across the origin, respectively. Students are expected to have previous knowledge of plotting & identifying ordered pairs, identify

This 16-slide PowerPoint presentation stresses quadrant location and the signs of the ordered pairs that fall into each particular quadrant. It assumes prior knowledge of plotting & identifying points in the coordinate plane. Examples lead students to try to first figure out on their own what a set of un-plotted order pairs have in common. The pairs will fall in the same quadrant and all x-coordinate signs will match as well as all y-coordinates matching. Students can take a 5-question quiz at t

This 22-slide PowerPoint presentation serves as an introduction to the coordinate plane. It begins by defining a coordinate plane and explaining its uses. Then construction of the plane, its parts, and terminology are covered. The rest of the presentation explains and simulates how to plot ordered pairs and how to determine ordered pairs for points already plotted. Fractional values and coordinates of zero are included in the simulation as well. The content is based on Common Core standard CCSS.

This is a short 10-slide PowerPoint presentation that shows how to convert a number line with positive numbers into a number line that includes both positive & negative numbers. It also describes opposites as well. Symmetry is described and used to extend the number line. You would probably spend about 15-20 minutes of class time to cover the content in this presentation. The content is based on Common Core standard CCSS.Math.Content.6.NS.C.6a under the domain Number System. Use the presentation

This 26-slide PowerPoint presentation serves as an introduction to negative numbers. It begins with a simulation about sea level and leads into real-world examples of negative numbers that include temperature, golf scoring, and personal budget surplus/deficit. Also covered are opposites and defining a zero point. This presentation can be covered in under 30 minutes. Use it for a full class lesson or for individuals who need to gain more understanding or missed the lesson. The content is based on
