LESSON PLAN TEMPLATE TITLE Chapter 15 Growing Patterns CONTENT AREAS What areas of mathematics does this lesson cover Sequences Growing patterns GRADE LEVEL Fourth grade KEY CONCEPTS Square blocks in a number of different colors Pencil Graph paper drawing supplies markers or crayons ROOM ARRANGEMENT Students sit at tables in groups of three MATERIALS NEEDED Square brown blocks Paper and pencil Graph paper drawing supplies markers or crayons EALRs and GLEs Make the connections clear and specific EALR 1 The student understands and applies the concepts and procedures of mathematics COMPONENT1 5 Understand and apply concepts and procedures from algebraic sense GLE 1 5 1 Recognize understand and extend a pattern of shapes and or objects or a pattern of numbers with a single addition subtraction or multiplication between terms Learning Goals Patterns involve step by step progressions called sequences The students can determine what the pattern will be at any given point by establishing the reoccurring sequence of the pattern pattern rule and using addition and subtraction PROCEDURES 50 min lesson 15 min Classroom management Introduction Classroom Management Before we start our lesson today I want to take some time to talk about classroom management issues Lately there has been a lot of talking and disrupting in class Do you remember our classroom social contract that we made at the beginning of the year Who can tell me what some of the classroom behaviors that we agreed on are What about rules and consequences Good memory Here is our contract Let s see if there is anything that we have forgotten Who would like to read our contract for me Have students take turns reading parts of contract out loud Well it seems like some of the behaviors that we agreed upon are being forgotten Would anyone like to talk about this Why do you think this has been happening What can we do about it Wrote ideas down on the whiteboard Good ideas Now who remembers the steps that I take when students disrupt Write on board You are correct First I will look at you then I will move near you next I will put my hands on your desk If you are still disrupting after that I will make an appointment to meet with you during work time and give you the opportunity to talk to me about what is going on and come up with some solutions Well things haven t gone farther than that point in this class yet thankfully Tomorrow we will go over the steps that happen if students are still disruptive after that point Now it is time to move on to our activity Activating Prior Knowledge Hello students I would like you to start thinking about patterns and the work that we have been doing with patterns Do you remember the designs that we made using pattern blocks discuss Where do we see patterns in our daily lives discuss Yes we see patterns all around us In nature in architecture in science Many artistic forms apply patterns Here is an example show example of a piece of art that uses patterns Patterns are also an important part of math They are used in computers and in prediction Do you know of any other areas of math where patterns are important 5 min Preassessment To start off I would like you each to draw a simple pattern Just take about 2 min to do this When you are done turn to your partner and explain the pattern that you have drawn Walk around the room and look at student drawings and listen to their explanations Disequilibration 5 min I have a pattern here to show you This pattern shows a sequence of dots Each pile is bigger than the next Who wants to predict how many dots are in this pile here point to a big pile towards the end of the sequence If some one can make the correct prediction address that if not tell them the answer I was able to predict this answer because I know the sequence of this pattern This is a pattern that increases by two s By adding two to each pile I was able to determine how many dots would be in this pile Write the number of dots underneath each pile and add 2 between them Activity Include formative assessments as appropriate Imagine that you were writing this for a substitute to teach Be detailed and specific Include specific questions you will ask students and some of the answers you would expect from them Include some other teacher talk 5 min Elaboration We are going to be practicing mathematical patterns with addition and subtraction When you are building a mathematical pattern each step is related to the previous step according to a rule In the pattern I just showed you the rule was plus two I have some square brown blocks here I am going to construct a pattern using these blocks Who would like to volunteer to come up to the front of the room and construct the first four steps of a pattern What was your pattern rule You can also make patterns using a subtraction rule When you do this you start out with a big number and gradually subtract Who would like to demonstrate a subtraction rule 15 min Crystallization Groups are shaped so that students with special learning needs in reading comprehension and writing are grouped with students that are gifted in this area Students with physical disabilities are grouped with a student that is capable of helping them if and when needed Students that can not write can answer the questions orally to the teacher Individual narratives will be provided in Braille for blind students For our next activity you will be working in groups of three s You will be responsible for working with and helping the student that you are in a group Remember the group etiquette that we practice in class and remember that helping each other creates an effective learning Now I would like you to work in groups of three students will be grouped at different ability levels I want one member of your group to start by making a sequenced pattern using the blocks the other two should not look while you construct the pattern When you are finished the other group members should guess what the rule of your pattern is Make sure that every group member gets a chance to construct a pattern After each of you have had one turn I want you each to use the graph paper and markers to draw out at least six sequenced patterns some with addition and some with subtraction You can come up with the patterns together but you each must draw out the patterns on your own Also write down what the pattern rule is You will be turning this in to me If you finish early and want to test yourselves try making a pattern
