Homepage   What we are doing in math right now.... Properties of Multiplication click here to find out more about the DISTRIBUTIVE, IDENTITY, COMMUTATIVE, and ASSOCIATIVE properties of multiplication. Click here for a video about the distributive property (only the first 3 or so minutes apply to our math) Multiplication:We started multiplication today, and we are using a method that is new to your children (and maybe you too!)  It is similar to the partial product approach, but it creates a foundation of true multiplication understanding.  Here is a link to an example problem of 14 x 23.  Once you fill in the chart as is seeon in the link, you simply take the sum of the numbers (200 + 30 + 80 + 12) to find the product.  Please let me know if you have any questions!  Thank you!  DIVISION: Long division help! Order of Operations:  help and practice problems.  PEMDAS or Please Excuse My Dear Aunt Sally can help you too. Algebra: a brief explanation of using inverse operations to solve b + 8 = 12  We are trying to isolate the variable (get it by itself)     - 8    -8  The opposite of adding 8 is subtracting 8, so we do it to both sides We are left with: b + 0= 12 - 8 b  = 4 3q - 1 = 14      + 1   + 1 3q - 0 = 14 + 1 3q  = 15  3       3 q =5  Area/Perimeter: click here for an interactive program to help with area and perimeter.  IN CLASS AREA AND PERIMETER Volume: in class web page Probability: spinner coin toss probability games  Place value: Rockin the Standards video and lyrics Standard form: 32,590.22 Word form: Thirty-two thousand, five hundred ninety and twenty-two hundredths.
