Unit 4 Study Guide
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.

Congratulations and Welcome!!!
Thank you all so much for welcoming our newest classmates with such warm smiles and applause. We had a great day of reviewing Unit 1 today so that our new mathematicians feel like they didn't miss out!
We started learning how to use the traditional method of long division today. Here are some helpful websites on long division:

Magic Squares
Great job on trying the enrichment lesson last night! I know some of you got frustrated trying to figure it out, but I'm proud of you for giving it a shot!
Tonight's homework is Study Link 1.4.
to play a factor game that is similar to the one we played in class. Make sure you follow the directions because it is slightly different from how we played. You can either play against the computer or with another opponent at home!
