Find Ratios educational ideas and activities
Introduce the concept of ratios. Start out by giving small groups of learners an assortment of colored cubes. Have them write a description of the materials that you gave them and then use this as a jumping-off point to talk about ratios and how to write them mathematically. Introduce the terms: part to whole, part to part, whole to whole, and whole to part.
What do fractions and ratios have in common? What is unique about fractions and what is unique about ratios? Lead a discussion and model some examples. Then, pose some questions and have your mathematicians set up the ratios. Check for understanding by having them set up a Venn diagram comparing ratios and fractions.
Rates, ratios, proportions, oh my! Use the distance equals rate times time (d=rt) formula to teach about rate, ratio, and proportion. How many miles were traveled in how much time? Set up the information in a proportion to get a unit rate, as in miles per hour. Use the chart provided to help young learners identify a pattern and to then set up a proportion to find the missing information.
Seventh-graders solve 20 various types of problems related to ratio and rate. They write ratios in simplest form for each given statement, to compare the area of two figures, and write two ratios equivalent to each ratio. Pupils express each statement as unit rate and determine the value of each ratio. This well-written activity provides many real-world examples, including the graph of the speed of racing motorcycles.
Middle schoolers explore the concept of slope in numerous ways and start to look at simple linear equations. They describe the slope in a variety of ways such as the steepness of a line, developing a ratio, using graphs, using similar triangles, and through ordered pairs. This lesson has an amazing collections of great ideas when it comes to exploring slope.
Middle school math masters use ratios to determine the missing dimensions of various HD television screens. They also compare different dimensions of screens and determine whether or not they fit the same ratio. They perform similar tasks with the ratio for old analog television screens. This four-page worksheet will keep learners engaged and reinforce understanding of proportional relationships.
Photograph prints are often ordered as 4" x 6", 5" x 7", or 8" x 10", but did you know that these sizes are not proportional? Math wizards compare the ratios using different methods, such as graphing, in order to discover this fact. A worksheet, several possible solutions, and an extension activity make this a well-designed lesson to use as a teaching tool or homework assignment.
For this trigonometric ratios worksheet, students solve and complete 10 various types of problems. First, they write the degrees listed in radian measure. Then, students find the exact ratios for each equation. They also find the value of x in each triangle and evaluate.
Demonstrating the concept of ratios with several simple examples (animals, fruit, girls and boys in class), Sal guides viewers through the process of finding and simplifying ratios. Even those who have a hard time grasping the concept of ratios will have an easier time listening to Sal's easygoing instruction.
Addressing the concept of reserve ratios, Sal outlines the necessity and purpose of regulating the reserves within the banking system. He describes how an ideal banking system stays liquid, whereas a chaotic banking system might experience a bank run. This video would be ideal in an economics lecture, or even in a history class addressing the bank runs during the Great Depression.
