Is it possible to add infinitely long decimals? As pupils complete the examples in the ninth lesson of this 25-part series, they determine that adding these decimals cannot be done without error. Their task is then to determine the size...

Build on your learners' confidence in quick addition as they discover strategies to add tens to two-digit numbers. After reviewing counting by 10's, they discuss tactics to add multiples of 10 to other numbers. They visualize how to...

Help your class discover the commutative property of addition with this exploration of the addition table. By folding and coloring the table, a symmetry is found that directs students to an understanding of this crucial mathematical...

Young mathematicians learn how scientific notation is meant to save time. Part 10, out of a series of 15, asks scholars to recognize the correct use of scientific notation and finish by adding and subtracting numbers using...

Students use microscopes to examine fly families and analyze their genetic inheritance. For this genes lesson plan, students also use the chi square for comparing genes and compare the class results as a whole.

Students explore the concept of probability.  In this probability activity, students use area to determine probability.  Students use charts and spinners to help determine the probability of events such as flipping a coin or...

Students determine speed by running or walking a given distance and dividing the distance by the time it took them to do so. They record their average speed and compare it with the speeds of other moving objects.

Third graders use addition to create numbers that are palindromes and organize their results to look for patterns. They make generalizations from patterns and practice reading large numbers and addition with regrouping.

Students view butterflies and participate in a butterfly activity to learn needed vocabulary. In this butterfly life cycle lesson plan, students access prior knowledge of butterflies.  Students listen to a butterfly life cycle book....

Seventh graders determine what makes a battery work. In this battery lesson, 7th graders brainstorm ideas about how they think batteries provide energy. They perform an experiment in which they work as a team to assemble a battery. They...

Here is a great problem-solving activity for young mathematicians. Intended solely for instructional purposes, the activity is appropriate for learners to add four numbers together. Not only must they add four numbers together,...

Students practice effectively interviewing a subject and then use that interview to create a movie.

Learners are taught how to add and subtract and use number sense to solve basic math problems. In this addition and subtraction lesson, students are being taught using theories from different philosophers in education. They are given a...

Students add integers using a number line. In this algebra lesson, students add one and two digit integers. They compare zero pairs and the addition of integers.

Third graders explore math functions by completing problem solving activities. In this division lesson plan, 3rd graders utilize the division strategies acquired earlier to divide multiple digit numbers by 4's. Students complete problems...

Students create a notebook with divisibility rules in it. For this algebra lesson, students write down the rules that determine the factors of a number. They continue to add to the book and use it to help them on their problems.

In this place value worksheet, students in pairs shuffle a set of place value cards and then lay them out face down on a table. Students then draw a card and place it under one of their place value cards.

Students investigate light and its energy. They discuss the properties of light, research how much light the moon absorbed on their birthday on a website, complete a graphic organizer, and create a kaleidoscope.

Pupils use estimation as a math strategy. Students estimate the number of small snacks that are presented to them. Pupils count the snack items after they have estimated how many there are, before the class snack on a daily basis.
