Solve Problems Involving Rates and Ratios


By Khan Academy

Watch this video as the instructor clearly explains how to solve a word problem involving finding unit rates. When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. See how you can apply this process to help you solve similar problems.

How to use Ratios and Proportions to Solve Real World Problems


By mrtedmartin

Instructor uses a Power Point presentation to demonstrate how to use ratios and proportions to solve problems real world problems. Unit rates are discussed and definitions are given. Solving unit rate problems are modeled and a calculator is used for computation.

Comparing rates

Speed translation | Ratios, proportions, units, and rates | Pre-Algebra | Khan Academy


By Khan Academy

This video takes us through some more advanced unit conversion problems. Here, we can see how to make multiple conversions in the same problem concerning speed. Take particular note of how the units change in each step. More importantly, note how, step by step, our units slowly change into the units we want for our final answer. If you are having trouble understanding why this happens, go to the key concept described at 2:20 in the video. Note that this only occurs when multiplying two quantities, not when adding them!

Grade 5 Math Lessons and Worksheets


By Lumos Learning

It is important for you as a parent to know what your child should be learning in grade 5 math. This is for you to be able to monitor your child’s progress and see if they are having any difficulty with the subject. If you supervise their learning process, then you can determine whether your child needs more help or tutoring. Having a clear idea of the math concepts that your child should be learning also gives you a chance to reinforce their knowledge. Familiarize yourself with the lessons that he or she is learning about so that you can help them anytime they need your assistance. The major topics that are included in grade 5 math are math strands involving whole numbers, decimals, fractions, measurement, plane figures, area and perimeter, ratio, scale, percent, average, graphs, rectangular prisms and cubes, volume, rates and speed, and functions and equations. Your child should develop competency in understanding problems concerning these math concepts. Your child should also be able to translate that knowledge into their problem solving skills. These problems should be applicable in the real world so that your child will be able to visualize and analyze the situation. Grade 5 math already includes using formulas and creating solutions for math problems. This is the introduction of the more complex math concepts and operations. It is preferable that you guide and aid your child as much as you can at this stage. The danger of having your child experience too much difficulty in the subject is that he or she will completely lose interest in math. You should try to avoid this and help your child develop a strong foundation in math concepts. As your child goes on to learn about harder math, you should also be more willing to give them assistance.
