Curated OER
How Hot Is It?
Fourth graders practice estimating temperatures. They practice in Celsius and Fahrenheit.
Curated OER
Little Magic Squares
Students and teacher talk about arrays of numbers like the ones in A Square of Circles. They check to see that the rows all have the same sum; that the columns all have the same sum; and that the diagonals have the same sum.
Curated OER
The Topsy-Turvy Twins
Fourth graders read the problem and brainstorm for ways to solve the problem - list these on the board for the students to refer to as they solve the problem. They work in pairs and focus on the strategy selected.

Tantalizing Tessellations Lesson III: Creating a Slide Translation
Students watch and discuss an M. C. Escher video, use what they have learned to explain and apply their knowledge of tessellations in order to create a slide translation, present their findings in a 12" x 18" poster, and explore...
Curated OER
Rescue the Pattern
Students describe a wide variety of patterns. They extend a wide variety of patterns. Students write rules for a wide variety of patterns. Students represent, analyze, and generalize a variety of patterns with tables, graphs, and words.
Curated OER
Step by Step
Students measure the rise and run of steps from a place that holds meaning for them. They write a reflection (in the form of a journal entry, poem, or short story) regarding this significant place.
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
Squirrel Challenge
Students utilize The Nature Park Adventure educational software program to Introduce Modelling, Including the Estimation of Angles.
Curated OER
Tunnel Traps
Pupils identify shapes that match specific shape descriptions involving a range of geometric terms and correct polygon names. They utilize a mathematics educational software program to gain practice.
Curated OER
Introduction to Graphical Representation of Data Sets in Connection with Nuclear Decay
Students record data, make observations, and share in experimentation and discussion of numerical experiments.
Curated OER
Spiders' Wheel
Students engage in a lesson which reinforces the concepts of clockwise and anti-clockwise rotation, while developing an understanding that angles are measured in degrees. They utilize a mathematics educational program to gain practice.
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
PSTV
Learners figure the amount of programs can fit into a certain time frame. The use of problem solving allows for the student to examine how things can occupy time. They measure the time frame for one program then use that amount to...
Curated OER
Coin Shake-Up
Students discuss problem and take turns in pairs, one tossing the coins while the other guesses whether the coins land with the same side up or different sides up. They record the results of each guess as same or different.
Curated OER
Rows of Numbers
Students generate patterns from a structured situation, find a rule for the general term, and express it in words and symbols. They also devise and use problem solving strategies in a systematic way.
Curated OER
Sensing Somethong
Students 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 activity, 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"...
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
A thousand seconds
Young scholars 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
Lots of Squares
Students work in pairs, to make a square on the geoboards with a rubber band (or draw one on the dot paper). It can be any size and in any location and share their answers with the class.
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.
