**Math**- We are beginning our Measurement Unit. Have your child help measure items around the house using appropriate tools. -Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes.

-Estimate lengths using units of inches, feet, centimeters, and meters.

-Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit.

Previous Skills:

-Partition a rectangle into rows and columns of same-size squares and count to find the total number.

-Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.

We are currently strengthening our understanding of how to decompose numbers. Students are working on using a variety of strategies to solve triple digit subtraction equations. Watch the videos below to gain a better understanding of the learned strategies!

Explain subtraction as an unknown addend

Explain subtraction using place value

-Add a string of numbers (up to 4 double digit numbers)

-Use repeated addition to represent an array (a set of objects arranged in rows and columns.)

-Recognize and draw shapes having specified attributes, such as a given number of angles or given number of equal faces. Identify and sort the following shapes by similarities and differences: triangles, quadrilaterals, parallelograms, rectangles, squares, pentagons, hexagons, and cubes.

-Telling time to the nearest 5 minutes using an analog clock and a digital clock.

Solving word problems using coins and dollars. Students must have a strong foundation of matching the visual representation of a coin, to the name and to the value.

So far this year, we have been laying the foundation for our current unit: Addition and Subtraction with double digit numbers. The expectation is for students show mastery of solving an equation using two different strategies and be able to explain why the strategy works. Please view the videos below to see the different types of strategies your child will be practicing. Please let me know if you have any questions about these strategies.

-skip counting by 2s, 5s, 10s, and 100s starting at any number between 1 and 1,000.

-Determining if a number is even or odd by pairing objects, counting by 2, or writing a doubles equation.

-Determining the value of the ones, tens, and hundreds place

-Representing numbers in a variety of forms: word form, standard form, expanded form, pictorial representation

This week we will continue to solve a variety of type of story problems.

This week, we will continue to establish a strong foundation of applying a variety of strategies to mentally add number within 20. We will use the number line to solve strategies, solve word problems with an unknown partner or an unknown total.

Previous Skills:

While this skill may seem like a review for many, these strategies will be applied later in the school year when we begin to add/subtract double digit and triple digit numbers.
