                           Rekenrek
                            10 Days

Day 1: Problem 1: Count all the beads on the rekenrek.
       Problem 2: What do you notice about the color of the beads
       Problem 3: What is another way besides counting by ones, you could count all the
       beads? (2’s, 5’s, 10’s)
       Problem 4: Ask a student to show you the number 17. Have another student come
       up and count out the beads a different way (ex. first student moved one bead at a
       time, the next student counted them out by one row of 10 and moved the 7 from
       the next row all at once)
Day 2: Problem 1: Have three different students show you how to make the number 29
        in three different ways. (one student counts by ones, next did two rows of 10 at
       one push then added the 9, third – pushed three rows of ten, then took one away)
       Problem 2: Play Quick Images- hide 33 beads behind a large piece of paper. Flash
       the beads quickly and have the students tell you how many they saw. (three whole
       lines which is 30 then just three red beads)
       Problem 3: Roll one dice. Then move over the number of beads you rolled. Ask the
       students “How many more beads would I need to make 15?” (you rolled 4, I would
       need 11 more to get to 15)
       Problem 4: How many groups of 5 are in the number 50?
Day 3: Problem1: Have three different students make the number 62.
       Problem 2: How many groups of 10 are in the number 49?
       Problem 3: Read this problem out loud, have the students come up and show you
       how to solve the problem using the beads. 18 + 20 = __
       Problem 4: Roll a dice. Show that number on the rekenrek. How many more do I
       need to reach the number 15?
Day 4: Problem 1: Quick Image 27
       Problem 2: Read out loud this problem. Have different students come up and act
       out each number on the rekenrek as you read the problem. 44 take away 16
       equals?
       Problem 3: 19 – 16 =
       Problem 4: 27- 15 =
Day 5: Problem 1: Quick Image 18
       Problem 2: Roll two dice, how many more do I need to reach 20?
       Problem 3: 20 + 5 =
       Problem 4: 11 + 9 =
Day 6: Problem 1: Have different students come up and make all the combinations of 10
       Problem 2: Missing addend 6 + __= 20
       Problem 3: How many groups of 10 are in the number 78
       Problem 4: Make up a story about a double decker bus. Ex. There is a double
       decker bus that drives around Washington DC picking up passengers that want to
       see all of the monuments. He stops at the first stop and there were six people who

       On the next stop two more people got on the top of the bus but two people got off
       the bottom. How many people are on the bus now? On the third stop, five people got
       off the top and moved down to the bottom because of the rain. How many people
       are on the bus now?

       Problem 2: Show me how to make 4 rows of 3. How many beads do you have?
       Problem 3: Show me how to make 3 rows of 4. How many beads do you have?
       Problem 4: Show me how to make 2 rows of 6. How many beads do you have?
Day 8: Problem 1: Roll two dice. How many more do I need to reach the number 20?
       Problem 2: Quick Image 21
       Problem 3: Decompose the number 88. How many tens and how many ones?
       Problem 4: 72-31 = ____
Day 9: Problem 1: Story problem: I went shopping with some of my friends at Dillard’s.
