Math
3-8-10 We are continuing our Measurement Cluster. This week we will learn volume and temperature. We have discussed these concepts earlier in the year with science, so your child has some background knowledge. Students will be able to use pictorial models to determine volume of solids. 3-1-10 This week we are focusing on metric length, mass, and capacity. Each student needs to be able to measure length using rulers, and estimate mass and capacity. We are also reviewing perimeter and area. When given a word problem, students need to be able to determine if perimeter or area is being used and solve the problem. 2-22-10 This week we are targeting customary capacity and conversions. We will continue to use the 1-2-3 Strategy for conversions. Example: 16 qts = ___ Gal - S -> L ÷
- 1 Gal = 4 qt
- 16 ÷ 4 = 4 Gal
After we cover capacity, we will be mixing conversions of customary length, weight, and capacity. (See below for more detail on steps 1, 2, and 3) 2-16-10 This week we are targeting customary weight and conversions. We will continue to use the 1-2-3 Strategy for conversions. Example: 8 lbs = ____ oz 1. L -> S (x) 2. 1 lb = 16 oz 3. 8 x 16 = 128 oz (See below for a break down of each step) 2-8-10 We are taking our Probability CBA Tuesday and then moving to Cluster 7 on Measurement. This week we are focusing on customary length and conversions. We will teach a three step method of converting. Example: 3ft = _____ in Step One: Decide if you are going from larger to smaller L -> S (Multiply) or Smaller to Larger S -> L (Divide). In this case we are going from larger (feet) to smaller (inches), so we are going to multiply. Step Two: Write the conversion factor. Make sure you always put the factor with one first. 1 ft = 12 in Step Three: Carry out the process (multiplication or division). 3ft x 12in = 36in So on your child’s paper, it will look like this: 3ft = _____ in 1. L -> S X 2. 1ft = 12in 3. 3 x 12 = 36 2-1-10 We are beginning our short Cluster 6 on Probability. Our CBA will be on Tuesday, February 9th. We will be discussing all possible outcomes with different situations. Graphs are also a big part of this test. Students will need to be able to read graphs and use that information to answer questions. Please go over the following terminology with your child: - Outcome - Combination 1-25-10 We have our Cluster 5 CBA on Wednesday, January 27th over Decimals. Make sure your child knows how to do the following: - Write decimals: standard (decimal), word form, and as a fraction - Look at a picture of base ten blocks/money and be able to write the decimal in many ways - Given a decimal, draw the base ten models - Order decimals from least to greatest and greatest to least (knowing which is less/greater) - Add and subtract decimals - Know how to put and read decimals on a number line Please review previous weeks' concepts with your children. 1-19-10 This week we are continuing to add decimals. We will begin to subtract decimals. This will be related to real life by using these decimals in a shopping game. Please practice with your children at the store on adding and subtracting decimals. Pull out a particular dollar bill and ask if you have enough money to buy a couple items. 1-11-10 This week we are relating what we know about decimals and fractions to our money system. We are also beginning to add decimals. We will show how to add using two colors on a 10x10 grid and then move on to the traditional algorithm. Go over the following fractions/decimals with your children. - ¼ of one whole = 0.25 - ½ of one whole = 0.50 - ¾ of one whole = 0.75 1-4-10 We are beginning Cluster 5 on Decimals. We will use our knowledge we just gained of fractions and relate them to decimals. We will learn basic facts about decimals, how to order them, and how to put them on a number line. Our CBA is scheduled for Wednesday, January 27th.Please continue to help your children at home as we do at school. Review the following terms with your children: - Decimals - Tenths - Hundredths 12-14-09 We are taking our CBA over fractions on December 16th. It will cover identifying fractions, equivalent fractions, word problems, and comparing fractions. Please review the information below with your child. 12-7-09 We are building more on fractions. This week we are going to be discussing improper and mixed fractions. Also, we are extending our knowledge of ordering fractions by placing them on a number line. Have your child give examples of the following. - Fraction - Equivalent Fractions - Ordering Fractions - Proper Fraction - Improper Fraction - Mixed Fraction 11-30-09 Now that we have discussed equivalent fractions, we are building upon that knowledge by comparing fractions. All of our representations are pictorial. We are going to be comparing different fractions using ½ as our benchmark. Please work on this at home with real life situations and use the following terms. - Greater Than - Less Than - Equal To 11-16-09 We have started Cluster 4 on Fractions. We will be reviewing what they learned in third grade as well as extending that knowledge further. All fractions that we will study are with pictures. We will be discussing equivalent fractions as well as comparing them to each other. Work with your child on the following vocabulary words: - Fraction - Numerator - Denominator - Equivalent 11-9-09 We are reviewing for our CBA on Thursday. It will cover division. Please continue to work with your child on thinking patterns with word problems. Use the links page of our website for helpful tools to use to practice at home. A great resource that we use in the classroom is dovewhisper.com. 11-2-09 This week we are working on our "7s" for multiplication. Please practice at least 5 minutes each night. We are continuing our journey in long division. This week we are doing BIG 7 with 3 digit dividends. We will start with 3 digit numbers that do not have remainders and move on to more difficult problems with remainders. Please practice these at home. Examples are attached below. Please go over the following vocabulary with your child: - Dividend - Divisor - Quotient - Remainder 10-26-09 This week we are working on our "12s" for multiplication. Please practice at least 5 minutes each night. We are discussing how to estimate with division. In addition, subtraction, and multiplication, you simply round to the nearest ten, hundred, or thousand. In division, you round to the nearest multiple of the divisor. Example: 500 ÷ 8 ˜ You round the 500 to 480 because 480 is divisible by 8. 480 ÷ 8 = 6, therefore 500 ÷ 8 ˜ 6 We are starting to do long division with a strategy called BIG 7. Below is a document showing BIG 7 with simple facts and BIG 7 with remainders. The students’ biggest struggle is determining what thinking pattern and process to use when solving word problems. We have now shown them all thinking patterns. Some and Some More (SSM): Addition Some Went Away (SWA): Subtraction Bigger/Smaller Difference (BsD): Subtraction Equal Groups Put Together (EGPT): Multiplication Equal Groups Taken Apart (EGTA): Division Please work with your child on word problems. Have them discuss what thinking pattern to use and why. 10-19-09 This week we are working on our "8s" for multiplication. Please practice at least 5 minutes each night. We are using our multiplication and division knowledge to detect patterns in tables. These patterns are called rules. For example: | Input | Output | | 1 | 7 | | 2 | 14 | | 3 | 21 | | 4 | ? | The rule/pattern would be multiplying by 7. Therefore the output of 4 would be 28. Please practice these with your child at home. 10-12-09 This week we are working on our "4s" for multiplication. Please practice at least 5 minutes each night. We are starting up division this week. Like multiplication, we will present several ways to approach division. We will link our documents to this website so that you can help your children at home as well.
10-5-09 This week we are working on our "9s" for multiplication. Please practice at least 5 minutes each night. We will continue our study of two-digit by two-digit multiplication. This week we will teach the traditional algorithm as well as review partial product box, bowtie, and lattice. On the bottom of this page, you will see files that demonstrate how to do all of these methods. Our Cluster 2 CBA is on Thursday, October 8th. Please practice these with your child. All fourth methods of working on multiplication are attached as files for you to view at the bottom of this page.
9-28-09
This week we are working on our "6s" for multiplication. Please practice at least 5 minutes each night. We are starting two-digit by two-digit multiplication using partial products. We will begin by showing arrays and move to the Partial Product Box. The attached Mobi document helps go over the steps to the Partial Product Box (located at the bottom of this page). Please help your child with this hard concept. Practice makes perfect. Try these problems: 33 x 17, 26 x 48, and 72 x 51 There is another file at the bottom that shows the "bowtie" procedure to help students with 2 digit by 2 digit multiplication problems. 9-21-09 This week we are working on our "3s" for multiplication. Please practice at least 5 minutes each night. We are continuing our unit on Multiplication. We are finding patterns in multiples. Ask your child to tell you the pattern in multiplying by 1, 10 and 100. 9-14-09 This week we are working on our "11s" for multiplication. Ask your child if they know the following vocabulary words: - factor
- product
- array
- multiple
We are also working on how to show multiplication problems in picture, word, and number form. For example: PICTURE- | * | * | * | * | | * | * | * | * | | * | * | * | * | | * | * | * | * | | * | * | * | * | | * | * | * | * | WORD- Four times six equals twenty-four. NUMBER- 4 X 6 = 24 8-31-09 This week we are working on the following topics: - place value (ones, tens, hundreds)
- comparing and ordering numbers (putting them in the right order on a number line, and using "greater than"/"less than" vocabulary)
- rounding
In Frisco, we teach math in clusters. Our first cluster is place value and spans the first three weeks of school. Students will learn to read, write, compare, and order numbers to the hundred millions place. They will plot whole numbers on a number line, as well as round numbers to the tens, hundreds, and thousands place. Students will also practice adding and subtracting larger numbers with regrouping. Our curriculum based assessment, or CBA, is tentatively scheduled for September 11.
