Lesson Plan 3

Concept: Using Chick-pea and Toothpicks to understand how shape and structure is important

Concept Questions:

	Why and how is structure so important?
	What is the importance in having structure in our lives?
	How can these shapes be useful in structure?
	Even though these shapes are different from each other, what is the most important things about them?
	How can we calculate the area, circumference, weight, etc. of the different shapes that we made?

Goals:

	For students to be able to name the different 3D structures and put them together
	For students to understand that it is important for them to have structure in their own lives
	To become more familiar with dimensions, volume, circumference, area etc…

Activities:

	(10 minutes) Warm-up activity: Review the names of 2D and 3D shapes and list them on the board
	Give each student some chick peas and toothpicks
	(5 minutes) Let the students work individually to see what 2D shapes they can make on their own (chick –peas will be used as corners and toothpicks as the sides)
	(10 minutes) Have students make 3D shapes when they feel confident enough making 2D shapes
	(15 minutes) Then, have 2 students work together to make a 3D structure of their choice as long as they can keep it together
	After that, call all of the students back for a discussion (let their shape dry and use a string to hang it on the classroom ceiling/under each shape, have them write their names and what they have decided to call the structure)
	(10 minutes) Discuss where in real life the students have seen these shapes like the ones they just made
	(10 minutes) Discus the question, what is the importance of having structure in our lives
	(25 minutes) Have them do some measurement activities to become more familiar with dimensions.

	Count the number of chick-peas and toothpicks on their structure model
	Have a “weight station” Using a scale, have them calculate the weight of the model
	Using a ruler, have them calculate the area of shape, circumference and volume in their groups of 2

(5 minutes) Survey

	How well did this experiment help you understand the concepts of measurement and structure?
	What were the good things about doing this experiment?
	What could be done differently?

Evaluation:

Teacher Evaluation:

	What specific management techniques that you used today, helpful? Not helpful?
	Did you have enough materials for each student to complete their project?

Student Evaluation:

	Make sure their measurements are correct to see if they understood how to find: volume, weight, circumference, and area of shape
	Look at the survey and change things according to best judgment

Did they all enjoy working with these materials?

Take notes on the class

	Are they working well individually? In their groups of two?
	How are their listening skills? Did they follow directions?
	Did they work calmly or did they play too much with the materials they were working with?
	Is this experiment the best way to get these concepts across to students
