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
Students 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
Pupils 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.
Curated OER
Big Steps
Second graders practice developing strategies for mental calculation when counting in 10s and 100s. They mentally perform calculations involving addition and subtraction to be able to state the difference between numbers by counting in...
Curated OER
Tap Your Feet
Students access a website to examine how to follow a pattern. They find their own heartbeats and tap along with the beat. They access a second website to design a class composition before showing how they keep the beat. They use...
Curated OER
Fold and Cut 2
Second graders make, name, and describe, using their own language and the language of geometry, everyday shapes and objects. They create and discuss geometric patterns which repeat (show translation), or which have rotational or...
Curated OER
Odd One Out
Ninth graders identify and describe in their own language, the following 2-dimensional shapes: square, circle, box, pentagon; classify objects by shape attributes. They then list a number of properties that distinguish squares from...
Curated OER
Who Plays What?
Ninth graders divide in pairs 3 cards with the words possible, impossible and certain on them. Ask questions of the class and get the students to hold up the word that describes the event (for example) Tomorrow it will snow. You have...
Curated OER
The Folding Problem
Ninth graders experiment with paper folding to create geometrical shapes. Students analyze the Copymaster of the problem. After the students have worked on their own for a while, stop them and discuss.
Curated OER
Fifty Toes
Students guess the subject of the given problem by reasoning. Then they discuss the ways that the problem could be solved by keeping track of their counting in 10s and showing their work.
Curated OER
A Square of Circles
Second graders practice calculations and working with even and odd numbers. They perform mental calculations involving addition. Students devise and use problem solving strategies to solve problems.
Curated OER
Jo's Table
Second graders work on the problem with a partner. They examine what they are supposed to be doing. They share the students's solutions making sure than they are looking for patterns along the diagonals.
Curated OER
Pigs and Ducks
Second graders use multiplication to solve problems. They use the multiplication facts for 2 and 4. Students combine operations to solve the problem and they devise and apply problem solving strategies.
