Young scholars examine the influence of interaction with other cultures and the environment in relation to calendars. They also look at the origins of the calendar we use every day.

Students examine mimicry as a survival strategy in repiles. They examine examples of the Mexican milksnake and the coralsnake in attempt to distinguish the differences in them. They discuss other species that use mimicry.

Students explore creating a self-assessment tool in a model classroom. Through the use of a video, students are observed engaging in peer assessment activities to generate a checklist. Students discuss the use of strategies a teacher can...

Students investigate test scores taken to obtain academic strengths and weaknesses. They practice looking at the scores in order to interpret the results. Students use time for class discussion and planning study strategies to target...

Mark Twain, the famous American author, is often studied in the school system. Use "The Prince and the Pauper" to analyze the differences between the text and its video version.  This lesson includes several culminating project...

Students use seconds, minutes, and hours. They then discuss the size of a thousand. After that they read time in digital or analogue form.

Students listen to Gill's story and determine how many number points she has. They then find the number of points their own name has and get into groups where all the name points are the same.

Fourth graders work in a group of 4 to make rectangle with a 12m length of string. They discuss its perimeter and how they would calculate its area. Then another group of 4 make another rectangle and estimate if the area would be greater...

Students explore mathematical problem solving. Given a case problem, students write a rule to solve problems involving decimal multiplication and division. They invent problems, share them with the class, and solve other student's...

Fourth graders complete multiplication, addition, and subtraction problems that all contain regrouping. In this regrouping lesson plan, 4th graders complete worksheets not provided.

Students use the lesson, "Squirt", to support students' development of multiplicative thinking. Squirt encourages students to anticipate multiplicative measurement relationships, e.g. three measures of A fit in B, by partially filling a...

Students listen to the problem read to them. They answer some simple questions using number sentences. They then compose a written record of the solution and share their approaches used.

Students attempt a problem that Students has the potential to have more than one solution. Hence the problem is accessible to a wide range of students. The problem is essentially about finding patterns and this is typical of a number of...

Learners begin the lesson by examining Census data from the state of Ohio from 1990 and 2000. Using a worksheet, they solve problems using the data and a calculator. They share their responses with the class and discuss what the data...

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.

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...

Students need to be able to calculate the volume and surface area of a cuboid as well as present a systematic list of results in order to justify the minimum case. The use of three factors of 100 is also important.

Students explore the making of circles and concepts related to them in geometry. The project is inquiry based will focus upon students making their own nametags. The construction is ideal for hands on students.

Eighth graders find connections between numbers in a table; use Pythagoras' theorem in a general algebraic form; and measure accurately from a scale drawing to find a method that might enable the helicopter to land inside a rectangular...

This unit introduces a number of important concepts relating to fractions. The first of these is that fractions represent parts of regions and sets and so are useful in a large variety of situations. Whole numbers are not enough by...

Learners use an Internet tool, "The Take-Away Bar" to solve subtraction problems by breaking them into parts. They write and solve comparison problems. Students make sensible estimates and check the reasonableness of answers. They use...

Students use rounding and compensating with whole numbers and explain how to use the empty number line to show additions and subtractions. They round and compensate in relation to decimal subtraction Background

Students explore the concept of absolute value inequalities and equations. For this absolute value inequalities and equations lesson, students discuss how to solve absolute value inequalities and equations through teacher led discussion...

Learners practice theories dealing with equals sign used as a balance, inequality symbols and practice utilizing a box or some other geometric shape to represent an unknown number. They assess numeracy problems embedded in language-rick...
