To Half or Half Not
Jump into equivalent fractions using these fun scenarios for mathematicians to solve. First, they use geoboards to find different ways to divide a rectangle in half. Then, an alien from the planet Fractional is after one half of their...
Curated OER
Draw the Other Half
How can you make the two halves symetric? Scholars use the concept of symmetry to complete five images which are only half-drawn. The fun part about this exercise is that they aren't copying geometric shapes. There is a face, sun, kite,...

Halves
Is it half? There are three sections to this introductory fractions learning exercise focusing on halves. First graders begin by coloring half of five basic shapes, each of which already is divided into two parts. Next, they examine four...
Curated OER
Halves and Fourths
Young mathematicians may not love fractions, but do they love sandwiches? How about cake? Use this visual fractions activity to represent fractions in a relatable way. Scholars start by coloring segmented shapes to indicate halves and...

Half-Life
Scholars shake their way to understanding half-life with the help of candy. They observe and record which side candy lands on to graph the exponential decay in the fifth lesson plan of seven integrating chemistry and algebra. Combining...
Curated OER
Doubles and Halves 3
Build mental math skills by teaching learners to double and half three-digit numbers. They start out by doubling one of seven double-digit numbers. Next, they discuss their strategy, and then practice doubling and halving 3-digit...
Curated OER
Halves And Fourths
Young learners start out by going to the board to draw lines through shapes to identify halves. Then they are given a square of paper and are directed to fold the paper into halves and then into fourths. They color the halves and fourths...
Curated OER
Fraction Halves
When you cut an object into two equal parts, you're creating halves or fractions. Introduce the numerator, denominator, and what they represent to your class. They review what a fraction is and then label the images that are halves.
Curated OER
Halves
Here is a clever way to have young mathematicians practice halving numbers. In each slide, two identical dice are shown. For example, one slide shows two dice with four dots each showing. The question is, "Half of 8 is......?" A good...

Telling Time: Telling Time: Half Hours
The whole class discusses the differences between the two clocks: digital and a clock with hands. They discuss the differences between the hour hand and minute hand. Students are taught telling time to the half hour. They are introduced...
Curated OER
Half Past Times
Learning how to tell time on an analog clock can be tricky for some kids. Start with the basics and teach them to determine the half-past time. There are five clocks shown. Learners draw in the times indicated, each time is half-past the...
Curated OER
Halves, Thirds, and Sixths
An excellent activity that effectively pulls together the concepts of area, fractions, and equivalent fractions! Using 3x2 rectangular arrays, 3rd graders are introduced to the concept of area in terms of square units. Building on this...
