Marvelous Math
Math Common Core:
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.
NBT.2 REad and write multi-digit whole numbers using base-ten numerals, number names, and expanded form.
CCSS.Math.Content.4.OA.A.3 Solve multistep word problems posed with whole numbers and having whole-number answers using the four operations, including problems in which remainders must be interpreted. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.

From last school year:
We will continue our measurement and geometry investigation focusing on different types of triangles. Here is another great website for your child to enjoy that covers many of the concepts s/he is learning in school: Math Is FUN!
In this unit students will:
● investigate what it means to measure length, weight, volume, time, and angles
● understand how to use standardized tools to measure length, weight, volume, time, and
angles
● understand how different units within a system (customary and metric) are related to each
other
● know relative sizes of measurement units within one system of units including km, m,
cm; kg, g; lb, oz; l, ml; hr, min, sec.
● solve word problems involving distances, intervals of time, liquid volumes, masses of
objects, and money, including problems involving simple fractions or decimals.
● make a line plot to display a data set of measurements in fractions of a unit (1/2, 1⁄4, 1/8) ● solve problems involving addition and subtraction of fractions by using information
presented in line plots
● apply the area and perimeter formulas for rectangles in real world and mathematical
problems.
● Recognize angles as geometric shapes that are formed wherever two rays share a
common endpoint, and understand concepts of angle measurement
● Measure angles in whole number degrees using a protractor
● Recognize angle measurement as additive and when an angle is decomposed into non-
overlapping parts, the angle measure of the whole is the sum of the angle measures of the parts.
Check out the following websites for some activities involving converting measurements in the customary system and measuring in inches for additional practice at home.

Your child was tested over the following competencies:
● Represent and read proper fractions, improper fractions, and mixed numbers in multiple ways.
● Represent equivalent common fractions
● Use mixed numbers and improper fractions interchangeably.
● Compare fractions and express their relationships using the symbols, >, <, or =.

Your child has also been busy learning different multiplication strategies. Check out the videos to see these different strategies in action so you can better help your child with his/her homework. :)Help With Fractions
Partial Product Multiplication Strategy
Partial Product Multiplication Strategy using a "box"
Lattice Multiplication Strategy
Your child worked on a task called Earth Day Project.
In this activity, students consider a real-world situation involving a set of data. Using the data,
students determine the pattern formed by the numbers in the data set. Then they extend the pattern
and use the pattern to make predictions.

CCSS.Math.Content.4.OA.C.5 Generate a number or shape pattern that follows a given rule. Identify apparent features of the pattern that were not explicit in the rule itself. For example, given the rule “Add 3” and the starting number 1, generate terms in the resulting sequence and observe that the terms appear to alternate between odd and even numbers. Explain informally why the numbers will continue to alternate in this way.Check out the following websites for more practice at home:

Your child is solving real world problems using a variety of tools. We have just begun to explore different division strategies including the partial quotient strategy. Check out the following youtube video to learn more about this strategy:
Partial Quotient Strategy Video
Your child is learning of more "strategy tools" to put into his/her math toolbox. We have used a variety of mental math strategies during our daily number talks to solve addition, subtraction, and multiplication and division problems. We are beginning to look at making place value arrays to help us solve two digit by two digit multiplication problems.
Please check out this video to see how to use arrays to help us solve multiplication problems:

The Concept of Balancing a Checking Account.
“Balancing” a checking account means comparing your records to the bank’s records to make sure they match. The process requires careful mathematical computation.
Your child will earn fake money for working hard and making excellent behavior choices. S/he will then be responsible for keeping track of his/her "money" by balancing his/her "checking account".
