Representing Half of a Rectangle

Doubles and halves are easier to cover when you apply them to familiar objects! Learners brainstorm things that come in pairs, followed by a discussion leading to doubles number sentences. Six word problems give partners practice as they...

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,...

Geometric shapes make great visual models for introducing young mathematicians to the concept of fractions. Looking at a series of four circles, students are asked to determine whether or not one half of each circle is shaded. To support...

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...

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...

Learners display correct time on improvised clocks. They  demonstrate the correct time to the half-hour. Everyone solves riddles concerning time.

What time is it? It's time to learn how to read analog and digital clocks! There are three analog and two digital clock faces here, each reading a time on the hour or half-hour. Learners examine and match them to the written-out versions...

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...

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...

Introduce young mathematicians to the concept of fractions by cutting shapes into pieces. The first video in this eight-part series starts by making a clear distinction between whole numbers and fractions. A circle is then used to...
