Terry Preston Claudia Fernandez Ortiz May 07 2008 Chapt 20 math lesson plan TITLE How big is a foot CONTENT AREAS What areas of mathematics does this lesson cover measurement GRADE LEVEL 2nd KEY CONCEPTS stand unit of measurement ROOM ARRANGEMENT students are in a whole group cluster except for the time when they are actively doing activities MATERIALS NEEDED Book Myller R 1991 How big is a foot New York Yearling Activity rulers scissors paper Door model cut out for teacher EALRs and GLEs Make the connections clear and specific 1 2 2 Understand differences between non standard and standard units of measurement for length and weight in the U S system EXAMPLES Describe non standard units that may be used for measuring length or weight Describe standard units that may be used for measuring length or weight Learning Goals What do you expect students to learn and be able to do from this lesson Given a measurement activity in which students use their feet as a non standard unit of measurement students will realize the importance of the standardized foot measurement and demonstrate their understanding by measuring classroom objects with a ruler PROCEDURES Label each step in the process Activating Prior Knowledge Disequilibration Elaboration Crystallization Introduction Preassessment Do some activity to see what your students know Tie it to EALRs GLEs 5min Good morning class for math today we re going to start by reading part of a story It is called How big is a foot What do you think the story will be about What do you think will happen student ideas So keep your ideas in mind as we read the story read story and stop at page with sticky note 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 Activity 1 10 minutes So what did the king use to measure the bed students his foot Well I measured Terry Preston Claudia Fernandez Ortiz May 07 2008 Chapt 20 math lesson plan something using a foot too and I need you to help me finish it So I m making a dog house at home and there is opening for a door but I want to add a flap to keep the cold air out at night draw model of dog house on board I would like your help in designing this flap Each one of you is going to get a piece of paper and cut out a shape to cover the door The king used his foot to measure the size of the Queen s bed now you re going to use your foot to measure the flap for the opening I measured the opening at home and it is one foot tall by one foot wide So now I would like you to cut out your shape so that it will fit the opening So the materials are over here on the table paper and scissors teacher will be available to assist students in cutting their opening 3 min So I have a model over here of the opening that I described to you earlier it is one foot tall by one foot wide Let s see if your shapes fit the door one by one students come up and hold up their cutout to the door After each students holds up their cut out teacher asks student what they used to measure their shape Disequilibrating Event 5 min Well does anyone know why the shapes you all cut out are different sizes and don t fit the opening even though they were are all measured with a foot students respond Well let s see compare your foot with your neighbors foot and I ll compare my foot with yours let s see what we find students compare feet So how does this relate to our door flap student responses They re different sizes Ok so let s see how the apprentice in our story measures the size of the bed finish reading story 2 min SO let s look at the last page again Does anyone recognize what the apprentice is pointing at with his hand students respond That reminds me pull out ruler this is the foot that I used at home Does anyone know what its called Its called a ruler and its length equals one foot It s not really the size of a foot because not all people have the same size feet but some adults may teacher uses ruler to prove to students that the width and height of the opening is one foot by one foot Why do you think the ruler was invented Teacher will take student responses and help students come to the understanding that there is a standard unit of a foot Elaboration Activity 2 10 minutes I have a box of rulers here for you to use I would like you to work in groups of two s to measure things in the classroom You can measure what you want but you each need to write down the measurement of the length of your desk the leg Terry Preston Claudia Fernandez Ortiz May 07 2008 Chapt 20 math lesson plan of your chair the length of the blackboard and the height of the cabinet You need to turn this in to me when you are finished Teacher will collect as summative assessment Crystallization Closure 3 min So what did we learn today Why do we use a ruler to measure A ruler is a standardized measurement for a foot Standardized means that everyone in America uses this same measurement Why do you think this is important Any questions POST ASSESSMENT Make direct links to learning goals EALRs and GLEs Rubric for summative assessment as described above in activity 2 GLE 1 2 2 Understand differences between non standard and standard units of measurement for length in the U S system Beginning Student took measurements of classroom objects using their foot rather than a ruler Developing Student took measurements of classroom objects using both their feet and the ruler Proficient Student took measurements of all four classroom objects using a ruler to write answer in feet Evidence Task for Positive Impact on Student Learning The evidence could be a comparison between the students pre assessments and summative assessments You should make that comparison as the teacher but also need to begin to ask students to reflect on what and how they learned those metacognitive questions by teaching self evaluation tools and routines Evidence is paper with measurements that students hand in from activity TEACHER REFLECTION What went well what would you do differently what advice would you give to someone who wanted to use this lesson ANNOTATED WEB RESOURCEs
