Review of February topics:
•Role of Properties in Algebra•Importance of Order of Operations in
solving algebraic equations•Mathemagic – writing algebraic expressions•Closed, Open-Middled, and
Open-Ended questions,and how to write them
Today’s Agenda• Pattern finding – Tiling
activity• Working with Perimeter and
Area• Using Algeblocks in the
Algebra classroom, grades 5-8
• Websites for ‘virtual’ Algeblocks!
• MCA test prep – sharing and ideas
Tiling Around the GardenCommit to an Outcome: By self •How many tiles must be added to form the 6th garden?•Each successive garden? (Recursive rule- each term of a recursive expression as determined by application of a rule or formula to its preceding terms)Expose beliefs: Share your answer with your group members.Confront beliefs: Decide on a recursive rule to share with the class.
Tiling Around the Garden (2)A table can help communicate the number of tiles that must be added form each successive garden.
Garden 0 1 2 3 4 5 6 7 8 …
Tiles
Tiling Around the Garden (3)Commit to an Outcome: By self •Physical objects can help find the explicit rule to determine the number of tiles around a garden of size n. •What patterns do you see when using the tiles?•What explicit rule (functional relationship - rule that determines the number of elements in a step from the step number)Expose beliefs: Share your answer with your group membersCommit to an outcome: With your groupDecide on an explicit rule and write your rule and a rational with a diagram of tiles to share with the class. Create a coordinate grid graph to display the data.

• Review perimeter and area of rectangles• The Puppy Pen Activity–Please work on this activity at your table; be
prepared to share your results with the group.–When finished, discuss how
You could use this with your students.
Perimeter and Area Activity
Using the Basic Mat• Compare the yellow rod(x) to the
green unit block.– How can you describe the dimensions
of the yellow rod in terms of the green rod?
– What is the perimeter of this piece?– What is the area of the yellow rod?
• Build rectangles with areas of 16 units, 18 units, 7 units.– Which numbers can build squares?– What numbers have only one
rectangular shape possible?– Why do some numbers have more
than one rectangular shape?
• Used to help students make the connection between concrete and abstract manipulations
• Helps develop comprehension of key concepts• Blocks represent constants (1) and variables: x,
x2, x3, y, y2, y3, xy, x2y, and xy2
• Three mats: Basic Mat, Quadrant Mat, Sentences Mat
• Factor Track allows students to use +/- factors & polynomial models in all four quadrants
Pattern Finding – Algeblocks Activity
Using the Basic Mat• Define the green block as a unit
representing 1• Use green blocks to build the
number 7• Use the green blocks to build the
number -3• Put one block on each side of the
mat; what numbers are represented? What happens when you combine the numbers?
Using the Basic Mat• Use the green blocks to show the
equation 5 + 3 = _____• Use the blocks to show the
equation 9 + (-7) = _____• Now build three ways to show
the number 4– Try using more than two numbers– Try using both positive and negative
numbers!
Using the Basic Mat• Use 12 units to build as many
rectangles as possible with different dimensions– Why are there so many ways? What
are the different ways?• Build rectangles with areas of 16
units, 18 units, 7 units.– Which numbers can build squares?– What numbers have only one
rectangular shape possible?– Why do some numbers have more
than one rectangular shape?
Using the Basic Mat• Use the yellow rod(x) to
represent the following situations:– Robert has five times as many
baseball cards as Kirsten does– Model x and -2x on your mat– In one month, Dion ate six times as
much fish as he did ham.
• In your group, design and describe your own situation– Share with the large group
Pattern Finding – Algeblocks Activity
Does this model represent 2x or x + 2?
x + 2
Use the blocks to represent these expressions:• 3x + 1• x – 6• 2x – x + 4 - 2
Pattern Finding – Algeblocks Activity
What is the relationship between these two blocks?
x x2
Use the blocks to represent these expressions:• x2 + x• 4x2 -7• 3x2
Pattern Finding – Algeblocks Activity
What expression does this represent?
3 = 3(x + 2)
= 3x + 6 x + 2Use the blocks to represent these expressions:• 4(x + 2)• -2x(3)• (2x)(x – 3)
