# Making 18 - Lesson for Kindergarten, Chapter - Composing Numbers

In the lesson titled "Making 18," kindergarteners will dive into an engaging exploration of composing numbers, focusing specifically on the number 18. This lesson is a critical part of the unit on Additional Practice with Numbers up to 20, providing young learners with the foundation they need to understand and manipulate numbers within this range.

Through activities like the "18 Candles Worksheet" and "Piecing Together 18 Worksheet," students will learn not just to recognize and count to 18, but also to understand the different ways numbers can be combined to reach 18. These worksheets are designed to enhance their cognitive skills in number recognition, counting, addition, and the concept of composing and decomposing numbers.

Understanding how to make the number 18 by combining smaller numbers is important for developing a strong number sense, a critical foundational skill in mathematics. This ability to think flexibly about numbers helps in problem-solving and builds a basis for future mathematical learning, including addition, subtraction, and beyond. By engaging in these activities, students will not only boost their numerical fluency but also gain confidence in their mathematical abilities, setting them up for success in their mathematical journey.

• ### Activity 1 / 18 Candles Worksheet

If you have just introduced your students to addition and subtraction in school, then you will find this worksheet incredibly helpful. Before your students will go on to solving algebra and other complicated mathematical problems, they will first need to master simple equations such as this one. In this printout, there is a birthday cake in the centre with the number 18 on it. Help your kids solve the simple problems, and then draw a line from the cake to all the ways of making 18.

• ### Activity 2 / Piecing Together 18 Worksheet

Using puzzles and bright colors to teach your preschoolers is one of the surest and best ways they can learn. Combine learning with some fun with this colorful worksheet. Look at the picture here with your students, and ask them what they see. There are simple mathematical equations on the puzzle pieces, and one equation is missing on each. Help your kids solve the problems, and then circle the puzzle piece that will make the bottom puzzle piece numbers equal 16.
