This week students will review standards 4.NBT.1 and 4.NBT.2 before moving on to standard 4.NBT.3. Standard 4.NBT.3 requires students to use place value understanding to round multi-digit whole numbers to any place. Students use number lines to visualize and understand the concept of rounding. They will be able to conceptually understand the rules for rounding and apply them to any number 1,000,000 or less. There is homework on Tuesday (workbook pages 21-22 and 33-34) and Thursday (workbook pages 41-42) this week. On Friday, we will have a quiz covering standards 4.NBT.1, 4.NBT.2 and 4.NBT.3.
4.1 Standards for the Week:
4.NBT.1 Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right. For example, recognize that 700 ÷ 70 = 10 by applying concepts of place value and division.
4.NBT.2 Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form. Compare two multi-digit number based on meaning of the digits in each place, using >, =, and < symbols to record the results of comparisons.
4.NBT.3 Use place value understanding to round multi-digit whole numbers to any place. Grade 4 expectations in this domain are limited to whole numbers less than or equal to 1,000,000.
4.2-Unit 5: Decimal Fractions
This week your child was introduced to their next standard of Unit 5: 4.NF.6. This standard requires the student to be able to convert a decimal fraction to a decimal (i.e.: 61/100 = .61). We will do this using 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!
4.2 Standards for the Week:
4.NF.6 - Use decimal notation for fractions with denominators 10 or 100. For example, rewrite 0.62 as 62/100; describe a length as 0.62 meters; locate 0.62 on a number line diagram.
5.1-Unit 1: Order of Operations
This week we will review standard 5.OA.1 and cover standard 5.OA.2 which require students to be able to correctly follow the order of operations when solving expressions (5.OA.1) and interpret both written and numerical expressions (5.OA.2) Students will write their "I can" statements in their math journals for each standard, take notes and record examples. Beyond the mini lesson, students will practice these standards at their other 4 math stations (math mini lessons are taught at the 'teacher station'. The kiddos have been doing a great job with it already! Students will have a quiz on these standards (5.OA.1 and 5.OA.2) on Friday, September 7th.
5.1 Standards for the Week:
5.OA.1 Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols. (Review)
5.OA.2 Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them. For example, express the calculation “add 8 and 7, then multiply by 2” as 2 × (8 + 7). Recognize that 3 × (18932 + 921) is three times as large as 18932 + 921,
without having to calculate the indicated sum or product.
