EE.3 - Apply the properties of operations to generate equivalent expressions.
warm-up
Write and simplify equivalent expressions.
1) 6( a + 4) + 12( a + 3)
2) Find the area of the whole figure.
Find the Greatest Common Factor - Use these terms as your two parts of an area model. What can you pull out as the GCF and what remains?
1) 20m + 15
2) 4n squared + 24n
1) 6( a + 4) + 12( a + 3)
2) Find the area of the whole figure.
- Part 1 Dimensions (2.5 by m)
- Part 2 Dimensions (2.5 by 4)
