4.1: This week we are beginning Unit 2: Multiplication and Division of Whole Numbers...
This week, your child will be introduced to their first two math standards of Unit 2, 4.OA.1 and 4.NBT.5. These standards require your child to interpret multiplication equations as comparisons (ex: 35 = 5x7; 35 is 5 times as many as 7 and 7 times as many as 5). Students will also be working on multiplication of whole numbers up to 4 digits by a 1 digit whole number, and multiply two digit numbers by another two digit number. Your child will take notes over this standard this week. Hands-on activities will be provided for your child in order to make real-world connections to the skills they are learning in class. There will be a quiz over 4.OA.1 and 4.NBT.5 this Friday, September 18th! The homework and standards for the week are written below.
4.1 Standards for the Week:
4.OA.1 - Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5 × 7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5. Represent verbal statements of multiplicative comparisons as multiplication equations.
4.NBT.5 - Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.
4.1 Homework for the Week:
- Tuesday (9/15/15) - IXL D6 practice for 20-25 minutes
- Thursday (9/17/15) - Multiplication Worksheet - Due Friday (9/18/15)
Recovery & Retake Information:
If your child has the option to retake the Unit 1 assessment or must retake, our recovery session will take place this Wednesday, September 16th during class time. The retake assessment will be on Thursday, September 17th.
4.2: This week we are continuing with Unit 4: Operations with Fractions...
This week your child was introduced to their next three standards of Unit 4: 4.NF.4a, 4.NF.4b., and 4.NF.4c. All three of these standards require the student to be able to multiply a fraction by a whole number. We will do this sing visual models and number lines. We will also practice this skill within word problems. Your child will be taking notes on the standards throughout the week in their Math Journals. Please remember that these are wonderful study tools that we encourage the students take home (as long as they remember to bring them back!) The students have been taking very neat, detailed notes that I know will makes awesome study tools! There will be a quiz over these two standards this coming Friday, September 4! These weekly check-ins let us see how your kiddo is progressing with the standards as we move through the unit :)
The standards and homework for the week are listed below!
4.2 Standards for the Week:
4.NF4 - Apply and extend previous understandings of multiplication to multiply a fraction by a whole number.
- 4.NF.4a - Understand a fraction a/b as a multiple of 1/b. For example, use a visual fraction model to represent 5/4 as the product 5 × (1/4), recording the conclusion by the equation 5/4 = 5 × (1/4).
- 4.NBT.4b - Understand a multiple of a/b as a multiple of 1/b, and use this understanding to multiply a fraction by a whole number. For example, use a visual fraction model to express 3 × (2/5) as 6 × (1/5), recognizing this product as 6/5. (In general, n × (a/b) = (n × a)/b.)
- 4.NF.4c - Solve word problems involving multiplication of a fraction by a whole number, e.g., by using visual fraction models and equations to represent the problem. For example, if each person at a party will eat 3/8 of a pound of roast beef, and there will be 5 people at the party, how many pounds of roast beef will be needed? Between what two whole numbers does your answer lie?
4.2 Homework for the Week:
- Tuesday (9/1/15) - IXL T1 & T2 (20 minutes of practice)
- Thursday (9/3/15) - Worksheet on Multiplying Fractions by Whole Numbers
5.1: This week we are beginning Unit 2: Decimals...
Students will be introduced to reading, writing, and expanding decimals. Students will look at standard and expanded form for this concept and will continue to incorporate the place value system into it. We will also be focusing on word problems in order to reinforce this concept on a regular basis. The standards for this unit and the homework for the week are listed below.
5.1 Standards for the Unit:
5.NBT.1 Recognize that in a multi-digit number, a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it represents in the place to its left.
5.NBT.3 Read, write, and compare decimals to thousandths. a. Read and write decimals to thousandths using base-ten numerals, number names, and expanded form, e.g., 347.392 = 3 × 100 + 4 × 10 + 7 × 1 + 3 × (1/10) + 9 × (1/100) + 2 × (1/1000).
5.1 Homework for the Week:
- Tuesday (9/15/15) - IXL G4 and G3 (do G4 first please!)
- Thursday (9/17/15) - Decimal Place Value Worksheet
General Math Reminders:
Have a great week!
