Learners will look at properties of 2D shapes as well as continue our measurement unit. Fifth graders need to be able to relate volume to the operations of multiplication and addition and solve real world and mathematical problems involving volume.
2D shape attributes You can practice VOLUME at home by: One of the main ways volume is used daily is when calculating drinking amounts. Soda pop is bought in 12-ounce cans or 20-ounce bottles. At the bar someone might order a pint of beer. Mayo Clinic recommends people drink a little more than 8 cups of water a day or eight 8-ounce glasses of water, about 1.9 liters. When you fill up your vehicle, the volume of gasoline your gas tank holds determines your purchase. Whether you fill up with gallons or liters of gasoline or other fuels, the amount is a volume calculation. On a smaller scale, when you fill up a gas can to take to another vehicle or to use the gas to power another device, you again use volume for determining the amount needed. The number of measuring cups and spoons in the average person's kitchen is indicative of how often volume is used when cooking. From the 1/4 cup of oil that is needed in a brownie recipe to the quart of chicken broth that is required for chicken noodle soup, volume is a measurement that is used in almost every recipe. Volume is used in most house-cleaning chores. When washing clothes, you add a specific mount of laundry liquid to the washing machine based on the load or volume of the tub and the clothes being washed. When using concentrated cleaning detergents, you add a specified amount of the cleaner to a clearly defined amount of water. Many times you apply a fixed volume of liquid to whatever you are cleaning. Water volume plays a huge part in water conservation. Water flow from a shower head is figured in gallons per minute. If you take a 10-minute shower, you'll likely use about 40 gallons of water, unless you have a water-saving showerhead. Water flow from sprinklers and hoses to determine water usage and conservation in your yard is also figured in gallons per minutes. Both are volume measurements.

Fifth graders are having tons of fun learning about volume. We've been building cubes and rectangular prisms, calculating volume, and using volume to determine the length, width and height of an object. We will also build volume robots this week.
Learners are reviewing the different rules for adding and subtracting decimals, multiplying decimals and dividing decimals. See the "cheat sheet" below. One great way to remember decimal rules is to think about money. This really helps learners understand decimals, fractions, and parts of a whole.
Decimal Cheat Sheet Learners continue to learn about long division and we work to "interpret" the remainder when working to divide. For example, if we have 32 students and each bus holds 20 people then we need to rent two buses based on our remainder. However, depending on the problem we work to understand what to do with our remainder.
Fifth graders evaluated their water log in order to calculate their water usage at home in one week. We determined the amount of water used in one week and multiplied the usage by 52 weeks to determine the amount of water used in a year. Learners were surprised to see how much water we use in our daily lives. They are finalizing their expo night project which includes these calculation and powerpoint projects which they shared with the fourth graders.
Water Resources Learners finish building their gaming trucks as we explore how division and multiplication are related..
