Patterned+Tables+(Multiplication+and+Division)


 * Day One:**

With teacher guidance, students develop a class chart showing the relationship between the number of batches of cookies made to the number of eggs needed for the given recipe:

3 eggs 1 tsp vanilla 3c flour 2 c sugar 1/2c butter 1/2 bag chocolate chips

Students should indicate how many eggs they would need for 0, 1, 2, 3 batches of cookies. Students' tables should look similar to this table:



Questioning:

Can you make a table that will help you figure out how many eggs you need? What are you recording in your table? To make one batch of cookies how many eggs do you need? To make two batches of cookies how many eggs do you need? For three batches? For four batches? How did you find the number of eggs needed for four batches of cookies? Can you organize this information into a table that tells the number of batches of cookies and gives the number of eggs needed? Tell me about your table. How would I use it?

In their math journals, students will create their own charts showing the realtionship between the number of batches of cookies and the number of cups of sugar in the recipe. You can have your high students try making a chart for the number of bags of chocolate chips.


 * Day Two:**

Have students work in partners to make charts using one of the items listed on the "Groups of..." chart from the multiplication unit. For example, they could make a chart showing the relationship between the number of triangles and the number of sides on those triangles, or the relationship between the number or horses and their horseshoes.


 * I have a sub for this day so I made a sheet to walk them through it AFM[[file:pattern+table+partner new.docx]]


 * Day Three and Four:**

Use the patterned tables word problems below to practice with your class. Keep pointing out that they should try to see the relationship between the two columns and not just focus on the numbers. Figuring out the relationship between the two columns wil help them to discover the pattern being used.

There are 28 problems.

The last few problems are input/output and I saw a really cute idea for making an "Input/Output machine" and I will try to create one for us to share.


 * Day Five:**
