Our Unit 4 Test is scheduled for Monday, December 8.
1. "Friendly numbers" - Remember that you can break numbers such as 72 divided by 3 into "friendly numbers" such as 60+12.
3 goes into 60 -- 20 times and 3 goes into 12 --4 times so the answer is 24 (20 + 4).
Practice doing that with other numbers such as:
56 divided by 4 (find friendly numbers for 56 that 4 will go into)
129 divided by 3
2. Practice long division with one, two, and three digit divisors.
3. Practice making estimates to division problems with decimals and then dividing with decimals...don't forget to line up your numbers and write neatly. Also remember that you can correct a division problem by multiplying the quotient by the divisor and you should get the dividend. (practice your vocabulary)
4. Work on interpreting remainders...know when to ignore them, when to report the remainder as a fraction or decimal, or when to round the answer up.

Unit 3 Study Guide
The Unit 3 Test will be on Friday, November 14. Don't forget, you can earn up to 3 extra credit points on your test if you turn in your Tessellation project on Friday!
1. Please know the definitions of the following:
Acute Angles - less than 90 degrees
Right Angles - 90 degrees exactly
Obtuse Angles - greater than 90 degrees, less than 180 degrees
Reflex Angles - greater than 180 degrees
Adjacent Angles - angles that are "next" to each other, they share a side and a vertex
Opposite/Vertical Angles - When two lines intersect, four angles are formed. The angles opposite each other are called vertical or opposite angles.
Polygons - closed figures with straight sides
Triangles - polygon with 3 sides and 3 angles
Equilateral triangle - 3 equal sides
Isosceles triangle - at least 2 equal sides
Scalene triangle - no equal sides
Quadrangle - polygon with 4 angles, same as a quadrilateral, which is a polygon with 4 sides and angles
Pentagon - polygon with 5 sides and angles
Hexagon - polygon with 6 sides and angles
Octagon - polygon with 8 sides and angles
Parallel lines - lines that run side by side and never meet
Congruent - having the same exact size and shape

Unit 2 Test
Great job on the test yesterday! Many of you tried the extra credit and received either 1 or 2 bonus points. Several of you also attempted the extra credit assignment last week on the Egyptian math method. If so, you received 1-3 bonus points on the Unit 2 test.
Today you will receive your graded test, along with your self-assessment checklist, study guide, and extra credit WS. These will all be attached to your current progress report. Please show the papers to your parents and have a parent sign the progress report.
