Megan Douglas Lesson Title: All Aboard! Date: March 5, 2015 Essential Question: Does a pattern exist when finding the different combinations of cars used to create different train lengths using Cuisinaire Rods? If so, what is it and how do you find it? Lesson Rational: In this lesson, the students will use Cuisinaire Rods to create different combinations while having different “car lengths” (individual rods) add up to “trains” (combinations) which are equal to the length of a larger car. The students will record the different combinations and how many there are for each car length and then look for a pattern by examining the numbers and a graphical representation of the results. Common Core State Standards: M08.D-S.1: Investigate patterns of association in bivariate data Anticipatory Set: To begin the lesson, have students brainstorm buzz words when they hear “pattern” and record on the 1st page of the flipchart using the pen tool. Show them on the 2nd page of the flipchart different patterns and have them work together to determine what the patterns are. Next, have 3 students come to the board and have them each draw their own pattern on the 3rd page of the flipchart using the pen/connector/fill tools. The first student must draw a pattern using shapes, the second student must draw a pattern using numbers, and the third student must draw a pattern using letters. Have the rest of the class look at the patterns and determine how each piece fits into the pattern…

Today you are going to learn the complete process of making crossbow trap. This is a thing that will not harm anybody, but will impress them that you made it yourself. I am also going to show you how to upgrade the trap so that it really hurts somebody, but I do recommend asking your parents before doing the upgrade. The materials that you will need to make the trap are: A toy crossbow, fishing wire, four sturdy sticks, a mega nerf bullet, tape, and string. For the upgrade you will need the…
