Curated OER
Sensing Somethong
Learners are taught that they can gather information about objects using the five senses of vision, touch, smell, taste, and hearing. They are told that some sensing, like sight, is done remotely. Students observe how a camera can...
Curated OER
Graphing the Past Using Today's Technology
Eighth graders research and gather information from such sources as Microsoft Encarta, World Wide Web sites, and other sources using computer software to collect data.
Curated OER
Mother May I?
Third graders measure distance using nonstandard units of measure. In this measurement lesson, 3rd graders measure a given distance through the use of the game "Mother May I?" Student gather and compare data on how many "giant steps" and...
Curated OER
Late-In-The-Year Counting
Students practice forward and backward counting. In this counting lesson, students calculate how many objects in a bag by counting forward and then count backward to check.
Curated OER
Gremlins
First graders investigate the missing numbers on an equation chart in order to practice their addition and subtraction skills. They work with sums up to twenty and use up to twenty objects to work with subtraction equations. They listen...
Curated OER
Reversing Numbers
Second graders solve a math word problem involving the addition of two digit numbers. They discuss the problem as a class, independently explore the problem, and discuss as a class the solution and how they organized their reversed...
Curated OER
Visiting Grandma
First graders investigate the aspect of time, including days of the week using a calendar. They use problem solving strategies and a monthly calendar to find a solution to the problem.
Curated OER
Taxi Fare
Students discuss what they know about taxis and how they charge. They read the problem and work in pairs focusing their thinking on the repeating pattern of twos. They then share their solutions and conclude with some class practice...
Curated OER
Weights
Students find an object that they estimate weighs 20g and check estimates on the balance scales. They read the problem and work in pairs focusing their understanding on the size of grams.
Curated OER
A thousand seconds
Pupils use seconds, minutes, and hours. They then discuss the size of a thousand. After that they read time in digital or analogue form.
Curated OER
How Many Strips?
Second graders investigate the measurement of 1 meter. They predict and measure how many strips of paper it takes to make exactly one meter. Students devise and use problem solving strategies to solve the problem.
Curated OER
The Farmer's Sheep
Students use problem solving skills, logical thinking, and their ability to work sequentially in order to solve an algebra problem. They listen to the problem read aloud by the teacher and devise a plan in order to solve the problem.
Curated OER
Grabbing CDs
Third graders determine the likelihood of an event. They randomly choose two CD's from a rack of eight. They determine all the combinations of CD's they can make and explain how they know when they have found all the combinations.
Curated OER
Parking Meters
Third graders are introduced to the problem with a short discussion about parking. They then solve with a partner. As they work ask questions that focus on the strategies they are using to make the calculations.
Curated OER
Garry The Greengrocer
Fourth graders are introduced to the problem by weighing objects on the balance scales. Use weights in both pans. (If you don't have access to scales use 2 containers and a child acting as the balance.) They then listen to the problem...
Curated OER
Adam's Watch
Third graders use their watches to tell the time while the teacher lists their responses on the board along with the reasons for them (set incorrectly, gain/lose time). They solve the problem in pairs and focus their thinking on the...
Curated OER
No-Three-In-A-Line Again
Learners interpret information and results in context while using words and symbols to generalize patterns. They use symmetry and angle properties of polygons to solve practical problems and identifying invariant properties under...
Curated OER
"ty" number
Second graders encounter the need to assess the code in English for tens is that the word ends in "-ty." They explore the meaning of two or three digit whole numbers to realize that the meaning of words like sixty can be decoded by...
Curated OER
Measurement
Second graders practice measuring and estimating the length of two objects. They answer questions related to these topics and then work together in parts to complete a worksheet.
Curated OER
Exploding Numbers
Students discuss how numbers increase when exponential growth is occurring. They view a video and compare exponential and linear growth with a graphing calculator.
Curated OER
Calendar Creations About the Civil War
Eighth graders research key events in the Civil War and create a calendar with illustrations and key events listed throughout the year.
Curated OER
Los Angeles Throughout the Years
In groups, 4th graders are given a recent decade to focus on and its impact on Los Angeles and to see how the city has changed over time.
Curated OER
Los Angeles Throughout the Years
Fourth graders study the history of the city of Los Angeles, investigating its variety of cultural traditions. They develop expertise on one specific decade in LA history.
Curated OER
Shaking Hands
Young scholars use diagrams or lists to show relationships. They also identify the pattern of triangular numbers. The mathematics behind situations provide a way of problem solving to examine the answers.
