# Cut Rectangles: Halves and Wholes - Lesson for Grade 2, Chapter - Fractions and Shapes

In the "Cut Rectangles: Halves and Wholes" lesson, designed for Grade 2 students, learners will delve into the fascinating world of Geometry, focusing on Fractions and Shapes. This lesson is an integral part of understanding basic mathematical concepts that will serve as the foundation for more complex topics in the future.

Students will begin by exploring Lines of Symmetry, learning how shapes can be divided into two identical parts. This concept is not only foundational in geometry but also enhances spatial reasoning and problem-solving skills. The "Cutting in Halves Worksheet" and the "Wholes and Halves Worksheet" will provide hands-on practice in identifying and creating halves, further deepening their understanding of fractions in a visual and tangible manner.

The "Let's Share Worksheet" introduces a practical application of halves and wholes, teaching students the importance of fair sharing and equality – a valuable lesson both in and out of the classroom.

Lastly, the "Cutting Rectangles with Alien Worksheet" adds an element of fun and engagement, using a fictional scenario to reinforce the day's lessons.

• ### Activity 2 / Cutting in Halves Worksheet

Ask your child if they know that whole shapes can be cut up and divided to form smaller parts. Explain how a whole shape, such as a square, can be cut into smaller pieces to form fractions. And, when a whole shape is divided into two equal parts, these parts are called halves. In the worksheet, there are pictures of examples of whole shapes, fractions, and halves. Look through the printout with your child and check all rectangles that are cut in two equal parts ½.

• ### Activity 3 / Wholes and Halves Worksheet

Fractions can be a cause of great stress to your students. After all, they have probably just only mastered the art of counting and adding, and now they have to deal with fractions and halves. Take some of their stress off by using this colorful worksheet to explain to them what whole shapes are, and how to easily identify halves. Ask them to identify the whole in the free printout and which shape is the half by drawing a line to the matching word.

• ### Activity 4 / Let's Share Worksheet

How much have you taught your children about sharing with other people? And, how good are they at sharing their things equally with others? Time to find out if all your lessons paid off! In this worksheet, it is time to have breakfast, and both brothers must get equal amounts of food. Ask your child to look through the pictures of food and check the boxes where the food is shared in equal halves.

• ### Activity 5 / Cutting Rectangles with Alien Worksheet

If your students are very interested in alien life and extraterrestrial occurrences, they would be even more interested in completing this exercise! The worksheet requires that your students help the little alien cut the rectangles into two equal parts (½). Your child must carefully follow the dotted lines on this tracing sheet to properly cut each rectangle in half.
