In this lesson, students will divide decimal dividends by two-digit divisors, estimating quotients, reasoning about the placement of the decimal point, and making connections to a written method.
In this lesson, students will solve division word problems involving multi-digit division with group size unknown and the number of groups unknown.
In this lesson, students will explore patterns in saving money.
Students learn the purpose of a fever in the body's immune system and how it protects the body against germs. The students continue to explore temperature by creating a model thermometer and completing a temperature conversion worksheet. They come to see how engineers are involved in designing helpful medical instruments such as thermometers.
Students solve problems that involve adding and subtracting decimals.
In this lesson, students describe the various ways people save money and explain how people can earn money. Students list the costs of their spending decisions and analyze the trade-offs of various spending and saving decisions.
In this lesson, students will apply their understanding of decimal number place value to order, compare and calculate speeds and distance animals travel.
Students develop an understanding of air pressure by using candy or cookie wafers to model how it changes with altitude, by comparing its magnitude to gravitational force per unit area, and by observing its magnitude with an aluminum can crushing experiment.
In this lesson, students are asked to recognize the equivalence of fractional tenths and decimals and to do simple decimal addition to find lengths both shorter and longer than 1.
In this lesson, students use their knowledge of the operations with decimals in order to plan a budget for a beach vacation.
In this activity, students filter different substances through a plastic window screen, different sized hardware cloth and poultry netting. Their model shows how the thickness of a filter in the kidney is imperative in deciding what will be filtered out and what will stay within the blood stream.
Purpose: Engages students and introduces elements needed for building a playground.
In “Playground Palooza”, students will take the role of a playground designer responding to a request for a new playground at the school. Students will learn about numerical patterns, reading and writing decimals, rounding decimals, adding, subtracting, multiplying, and dividing decimals, converting measurements, volume, measuring volume, relating volume, coordinate planes, and attributes of 2D figures. Students will determine the total area of the new playground, determine the total area for each structure you want included on your playground, determine the volume of sand needed for the sandbox, use at least three playground structures, create a table of equipment and materials including company name, cost, quantity, and totals, create a coordinate system to display the center point for each structures or area on the playground, and submit a blueprint of their playground design.
***NOTE
This PBL was created before NC adopted the NC standards for Math. Therefore this PBL also addresses: rounding decimals.
Students observe and discuss a vacuum cleaner model of a baghouse to better understand how this pollutant recovery method functions in cleaning industrial air pollution.
As the first engineering design challenge of the unit, students are introduced to the logic for solving a maze. First they observe a blindfolded student volunteer being guided through a classroom maze by the simple verbal instructions of another student. In this demonstration, the blindfolded student represents a robot and the guiding student represents programming commands. Then student groups apply that logic to program LEGO MINDSTORMS(TM) NXT robots to navigate through a maze, first with no sensors, and then with sensors. A PowerPoint® presentation, pre/post quizzes and a worksheet are provided.
Students observe and discuss a cup and pencil model of a cyclone to better understand the science behind how this pollutant recovery method functions in cleaning industrial air pollution.
In this interactive resources, students walk step by step through the process of multiplying decimals.
The area model can be used when multiplying any two numbers, including decimals. This video demonstrates how to multiply using the area model when a decimal is involved.
This short video and interactive assessment activity is designed to give fifth graders an overview of decimal word problems.
This short video and interactive assessment activity is designed to teach fifth graders about multiplying decimals by multiples of 10.
This grade 5 unit of number and operations lessons explores multiplying and dividing decimals through 8 hands-on activities and 8 worksheets.
