Below you will find information for all math groups for this coming week. Please scroll down to your child's math level (they are in order and color coded - 4.1 is green, 4.2 is purple, and 5.1 is grey).
4.1 Math Curriculum- Unit 5: Fractions and Decimals
- Students will be learning about equivalent decimal fractions ( ex: 2/10 = 2/100) - 4NF5
- Students will be learning how to add decimal fractions, both with like denominators and unlike denominators (ex: 2/10 + 3/10 = 5/10 , 3/10 + 40/100 = 7/10 or 70/100, and 5/10 + 12/100 = 62/100). - 4NF5
- Students will be learning how to write decimal fractions in decimal notation (6/10 = 0.6) - 4NF6
- Students will have a quiz on 4NF5 & 4NF6 on Friday, February 24th.
4.1 Standards for Unit 1:
*Focus standards of the week will be bolded
4.NF.5 - Express a fraction with denominator 10 as an equivalent fraction with denominator 100, and use this technique to add two fractions with respective denominators 10 and 100. For example, express 3/10 as 30/100, and add 3/10 + 4/100 = 34/100.
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.
4.NF.7 - Compare two decimals to hundredths by reasoning about their size. Recognize that comparisons are valid only when the two decimals refer to the same whole. Record the results of the comparisons with the symbols >, =, or <, and justify the conclusions, e.g. by using a visual model.
4.1 Homework for the Week:
- Tuesday (2/21/17) - Workbook pages 667-668 (additional practice - R5 & R6)
- Thursday (2/23/17) – Workbook pages 651-654 (addition practice - IXL T2 & T11)
- Friday (2/24/17) - Weekly Standards Quiz on 4NF5 & 4NF6
4.2 Math Curriculum: Unit 1 (now in the first unit of 5th grade math)
Order of Operations and Whole Numbers
- Students will be introduced to the Order of Operations, again, this week. You might recall, I did a mini-unit on this standard earlier in the year. This time, I will dive deeper into their understanding of the order of operations, numerical expressions, as well as numerical reasoning.
- MGSE5.OA.1 Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols.
- MGSE5.OA.2 Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them.
- MGSE5.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.
- MGSE5.NBT.2 Explain patterns in the number of zeros of the product when multiplying a number by powers of 10, and explain patterns in the placement of the decimal point when a decimal is multiplied or divided by a power of 10. Use whole-number exponents to denote powers of 10.
- MGSE5.NBT.5 Fluently multiply multi-digit whole numbers using the standard algorithm (or other strategies demonstrating understanding of multiplication) up to a 3 digit by 2 digit factor.
- MGSE5.NBT.6 Fluently divide up to 4-digit dividends and 2-digit divisors by using at least one of the following methods: strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations or concrete models. (e.g., rectangular arrays, area models)
- Tuesday (2/21/2017): Error Analysis Sheet from Unit 7 Assessment: Due Thursday
- Thursday (2/16/2017): IXL O.4
- Friday : Standards Based Quiz: 5.OA.1
5.1 Math Curriculum - Unit 5/6: 2D Figures & Volume & Measurement
- Units 5 and 6 will be combined. Unit 5 (2D figures) if VERY simplistic/short, and the very few standards that make up that unit make more sense to be combined with Unit 6 volume standards. Standards will be re-organized in a logical sense.
- Students will be practicing their metric and customary conversions this week. The foundation of this standard in laid down at the end of the year of 4th grade math, so we are picking up there and practicing more difficult conversions. This will help us with our conversions/calculations for the rest of the unit- 5MD1
- Students will have a quiz on 5MD1 on Friday, February 24th.
5.1 Standards for Units 5/6:
*Focus standards of the week will be bolded
Unit 5 Standards:
5.G.3- Understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles. (Will be paired with 5MD3)
5.G.4- Classify two-dimensional figures in a hierarchy based on properties (polygons, triangles and quadrilaterals). (Will be paired with 5MD4)
Unit 6 Standards:
5.MD.1- Convert among different-sized standard measurement units (mass, weight, length, time, etc.) within a given measurement system (customary and metric) (e.g., convert 5cm to 0.05m), and use these conversions in solving multi-step, real word problems.
5.MD.3- Recognize volume as an attribute of solid figures and understand concepts of volume measurement. a) A cube with side length 1 unit, called a “unit cube,” is said to have “one cubic unit” of volume, and can be used to measure volume. b) A solid figure which can be packed without gaps or overlaps using n unit cubes is said to have a volume of n cubic units. (Will be paired with 5G3)
5.MD.4- Measure volumes by counting unit cubes, using cubic cm, cubic in, cubic ft, and improvised units. (Will be paired with 5G4)
5.MD.5- Relate volume to the operations of multiplication and addition and solve real world and mathematical problems involving volume. a) Find the volume of a right rectangular prism with whole- number side lengths by packing it with unit cubes, and show that the volume is the same as would be found by multiplying the edge lengths, equivalently by multiplying the height by the area of the base. Represent threefold whole-number products as volumes, e.g., to represent the associative property of multiplication. b) Apply the formulas V = l × w × h and V = b × h for rectangular prisms to find volumes of right rectangular prisms with whole-number edge lengths in the context of solving real world and mathematical problems. c) Recognize volume as additive. Find volumes of solid figures composed of two non-overlapping right rectangular prisms by adding the volumes of the non-overlapping parts, applying this technique to solve real world problems.
5.1 Homework for the Week:
- Tuesday (2/21/17) - Study measurement conversion chart ; Metric/Customary conversions WS (only do those that are circled)
- Thursday (2/23/17) – IXL Z16 & Z18
- Friday (2/24/17) - Weekly standards quiz on 5MD1
We hope that you have a great week!
