Eureka Math

Kindergarten

Module 1

Lesson 14

At the request of elementary teachers, a team of Bethel & Sumner educators met as a committee to create Eureka slideshow presentations. These presentations are not meant as a script, nor are they required to be used. Please customize as needed. Thank you to the many educators who contributed to this project!

​

Directions for customizing presentations are available on the next slide.

​

How many ears do you have? Write the number. How many heads do you have? Write the number. How many feet do you have? Write the number. How many wings do you have? Write the number. Stand with 2 friends. How many noses are in your group? Write the number. Draw something that has 1 ear, 2 heads, and 3 feet. Show your friend your picture.

​

Concept Development (27 min)

Please take your linking cubes out. Pick up a cube. How many cubes are in your hand?Write 1 in the air.

Pick up another cube, and join it to your first one. Pick up another and join it. How many do you have now? Write 3 in the air.

Watch how I take my tower apart. How many cubes do I have in my hands?

Did I pick up any more cubes? Did I drop some?

​

Concept Development

So I still have 3 cubes in my hands, but I made my 3 tower into a 1 tower and a 2 tower. Take your tower of 3 and show me how you can break it into a 1 tower and a 2 tower.

Watch me put my parts together to ake a tower of 3 again. There is a special math way to write what I just did. 3=1+2 and 3=2+1.

This is called a number sentence.

Concept Development

I’m going to draw some cubes on the board. I will color 2 squares red. I will color the rest blue. How many cubes are in my tower?

How many red? How many blue?I will write it the Math Way. Here is our number sentence. 3=2+1

Can we do this with other things? (Draw 3 balls. Put stripes on one) How many balls are there? How many stripes? No stripes? Now we will practice finding the parts of three and write number sentences on our Problem Sets.

Debrief (5 min)

• How many are in your tower all together?
• What are the parts of your tower?
• How would we say that as a number sentence?
• 3 is the same as ________ and __________.
• Could we break bigger towers into parts and make number sentences to match?
• When have you taken something whole and broken it into two parts?
• If you put the parts together again, do you get something whole again?
