Math

Math News:
We have focused on addition, securing double facts, combinations of 10 and subtraction. We are now focusing on telling time, counting money and standard measurement with inches and centimeters. Place value is a continued focus as well.

Mathematics Number and Numeration: Students will: • Read, write, count, order numbers to 10,000 • Skip count by 1s, 2s, 5s, 10s, 25s and 100s • Demonstrate proficiency with all addition and subtraction facts through 10 + 10

Data: Students will: • Collect, organize data or use data to create charts, tables, graphs and plots • Make exchanges between coins and bills • Tells time to 5 minutes

Geometry: Students will: • Measure length to nearest inch and centimeter • Identifies, describes, and compares 2 and 3 dimensional shapes

Algebra: Students will: • Can find an unknown in a simple number sentence



== Please review your child's assessment with them when it comes home. It would be good practice for them to fix their errors. Please refer to the parent letters to aid you with homework support and questions. When homework comes home, it would be appreciated if your child could try their best to return it the next day. Please feel free to write any comments on the homework if your child has any trouble with it. Homework should just be extra practice to what we are doing in class and not stressful for you or your child!! ==

Partial Sums Addition: **The Partial Sums method is a two-stage process.** **In the first stage one looks at each column** **(left to right)** **and** **add up the place values** **represented by the digits in that column.** **In the second stage those partial sums are added together.**  Example Step-1: Add up the hundred place =500 345 + 234  Step two: add the _  __tens place. =70__ __Add 100s__ __500__ __Add 10s__ __70__ __Step-3: add up the__ __Add 1s__ __+__ __9__ __ones place =9__ _  Add partial 579 Step-4 add all the sum  partial sum to find answer. =579 http://www1.teachertube.com/viewVideo.php?video_id=52663&title=Partial_Sums_Addition&ref=bpeavey Partial Differences: || The "partial differences" method, is again a two-stage method. We operate first on each column individually, keeping track ofthe sign if a borrow would be needed, and then we combine the results using mental arithmetic. With this method, for 325 - 58 the second stage involves the mental arithmetic 300 - 30 - 3 = 267. || || ||

Example Subtract 100's: 300-100 =200 325 Use a "+" sign because the - 154 bottom number is smaller _ +200 Subtract 10's: 20-50 = 30 -30 Use a "-" sign because the + 1 top number is smaller ___ 171 Subtract 1's: 5-4 = 1  Use a "+" sign because the bottom number is smaller Total the "partial differences" to find your difference http://www1.teachertube.com/viewVideo.php?video_id=173586&title=Sample_Problem_of_Partial_Differences

= Math Games: = <span style="font-family: 'Lucida Console',Monaco,monospace;"> The below sites are from our Everyday Math Program. Your child has played many of these games in our room this year. They would be great for a family game night! You may use a deck of playing cards, taking out the Ace, Jacks, Queens, and Kings and use dice if you have them. We also added some other fun math sites, enjo y!
