Bunche                               164th Park Avenue                               Markham, Il. 60426                               708-333-6625 Objectives:The second grade students will:1. Know the place value of the ones and the tens.2. Know how many ones are in one ten.3. Be able to write numbers using more than one place value.Materials:Cuisenaire rods, counting sticks, place value charts, and an overhead projector.Strategies:Tell the students to count the sticks as you hold up the sticks in front of the class.  Once the ten sticks have been counted, put a rubber band around them. Have the students count four more sticks.  Ask the students, "How many sticks am I holding?"  "How many tens are there?"  "How many ones?"  Do several more examples using the counting sticks. Present the cuisenaire rods to the students.  Place on the overhead projector one orange rod and ten white rods.  Tell the students that you want them to count the white rods as you place them on top of the orange rod.  Ask the students, "How many white rods does it take to make one orange rod?"  Then, say to the students, "We're going to call the orange rod the ten rod and the white rod the one rod."  Draw on the board a place value chart.  Then have a student come to the front of the class and place two orange rods and six white rods on the overhead projector.  Ask, "How many rods are placed on the projector?"  Once the answer is given, ask "How many ten's rods are there?"  Write that answer in the ten's place on the place value chart.  Next ask, "How many one's are there?"  Write that answer in the one's place on the place value chart.  Do several more examples. Give each student a place value chart.  Tell the students to place the correct number of rods on their chart in the correct position as you give them a number.Do several more examples using the cuisenaire rods.For more practice give the students a worksheet concerned with the place value of the tens and the ones.`
