This is the study guide that I use to prepare students (7th grade) for the Chapter Test on Geometry. This contains great topics to prepare student for finding measures of central tendency and variation and finding probability and making predictions. Here are the topics that is covered on the study guide: Probability of a simple event Experimental Probability and Theoretical Probability Population and Sample Central Tendency (Mean, median, mode) Variation (Range, interquartile range) Effects a

This is the study guide that I use to prepare students (7th grade) for the Chapter Test on Constant of Proportionality. This contains great topics to prepare student for graphing and is a great review of unit rates! Here are the topics that is covered on the study guide: Describe if a graph, table, verbal description is proportional and why Identify the Constant of Proportionality from a graph, table and verbal description Write a proportional equation using the Constant of Proportionality Use

This worksheet separates the three types of scale models and drawings questions that students typically see. There are the normal problems, the problems that ask for the students to find the scale and problems that involve dimensions. This worksheet really helps the students see the difference between the questions and how to best solve each different question. It allows students to clearly see the difference between the questions. If you need the document in a PDF, just message me and I can ar

Exponent practice worksheet where the powers are greater than 2 and some of the base numbers are negative. I like to use this to get students to understand that difference between having a negative base in parenthesis and a negative base without parenthesis.

This is the study guide that I use to prepare students for the Chapter Test on Adding Subtracting Multiplying Dividing Decimals and Fractions. These problems have negative numbers intermixed. Here are the topics that is covered on the study guide: Add decimals with negatives Subtract decimals with negatives Multiply decimals with negatives Divide decimals with negatives Add fractions / mixed numbers with negatives (some with improper fraction answers) Subtract fractions / mixed numbers with neg

This is the study guide that I use to prepare students for the Chapter Test on Rates and Proportions. These problems have negative numbers intermixed. Here are the topics that is covered on the study guide: Calculate Unit Rates Identify if two ratios are proportional Calculate for a missing value in a proportion Set up and solve proportions from word problems Set up and solve proportions for scale problems Set up and solve proportions for dimension problems Set up and solve proportions to find

I use this sheet for students to record their work and answers for activities that I use in the class. It helps my students organize their answers and makes it easier for me to track the students' progress and work.
