Intooba Model Value Challenge Work in a group or individually. Printable worksheet and pencil needed. The Challenge: Two ways to play Version 1: The primary participant decides how players will get to the value of each colored rod starting with the shortest, or green, rod. Once the values of all rods in the design are reached, students or players add up the value of the model. Version 2: Alternatively, the model can be given a total value, and the participants need to work backwards to find viable values for the component pieces. Establishing Values: Values for each component may be established in any way. Here are some ideas for establishing component values. •Take the smallest value of three rolls, and multiply it by 2 •Select the first odd number you get •Select the first even number you get •The value of the green rod is 5x+4y, where x is your first even number, and y is your first odd number •Square the first odd number you receive •Take the average of the first three even numbers •In six rolls, add the highest two even numbers and the lowest odd numbers •Multiply the first odd number by 3.5 •Multiply the first even number by 100 In this way, the values for all the rods are set prior to students working on completing the actual value of the model in front of them. Alternatively, the primary participant could give a total value for the model presented, and either present options for rod values, or ask students to design their own parameters that would work within the model specifications. The Challenge: Version 1 The Challenge: Version 2 Need pencil, scratch paper Need pencil, scratch paper 1. The player(s) are presented with a completed model and the total value of the model. 1. The player(s) are presented with a completed model and the appropriate die for their math level. 2. The player(s) may be given values for some components of the model or none at all. Establishing the Total Value of the Model 2. Player(s) There are: green rods complete1. the I am the red rod: find my value by: 2. red rods component pa- purple rods 3.

I am the black 90 degree connector: find my value by: = x number of green rods 1. value of green rods 3. The player(s) work the problem backwards to = x number of red rods 2. value of red rods establish potential values for all of the models Rod Values: = x number of purple rods 3. value of purple rods components. 3. use the defined parameters and die to I amPlayer(s) the green rod. I am worth: = x number of yellow rods 4. value of yellow rods I am the red rod. the I am worth: calculate value for each component. 5. value of orange rods = x number of orange rods Establishing Rod Values: I am the green rod: find my value by: I am the purple rod. I am worth: I am the yellow rod. I am worth: 6. value of blue rods x number of blue rods = I am the orange rod. I am worth: 7. value of 60° connector x number of 60° connector = I am the blue rod. I am worth: 8. value of 90° connector x number of 90° connector = I am the black 60 degree connector. I am worth: I am the black 90 degree connector. I am worth: Now, add up your totals in 1 to 8 This is the value of your model: 4. Using the defined values the player(s) calculate the total value for the model. Multiplying the number of components by their value and then adding those values together to get the total value of the model.
