Issue B: 3-Digit Column Addition
Students use newspaper column addition to add 3-digit Numbers with incomparable Oregon more exchanges. A gradual release mold helps students become independent with these multi-step problems.
Topic C: 3-Digit Column Subtraction
Students use column minus to subtract 3-digit numbers with one or much exchanges. A gradual release model helps students become self-directed with these multi-step problems.
MODULE 6. Foundations of Multiplication and Division
Issue A: Formation of Equal Groups
Students work with monovular real-world objects to form equal groups given either the number of groups or the number of objects to put off in each group. They also determine the telephone number of groups, the number of objects in each aggroup, and the total number of objects. Students relate repeated addition number sentences to visual representations of coequal groups.
Topic B: Arrays and Equal Groups
Students work with purloin objects in arrays to determine number of columns/rows, number of objects in each column/dustup, and total number of objects. They use repeated improver to represent arrays, look at an array both as a set of rows and a circle of columns.
Topic C: Rectangular Arrays as a Foundation for Propagation and Division
Students move from a collecting of objects organized in an array to arrays composed of a grid of squares. As in the early topic, they determine the number of objects in each column/row and the entire number of objects, Eastern Samoa well as using repeated addition to represent the array.
Topic D: The Meaning of Level and Odd Numbers
Tally two equal addends to take an even number sum
Learn that even numbers are the sum of two isometrical addends. State the number of items shown then doubled the amount and state the total. then, practice determination the sums of equal addends
Span objects to determine whether the total is even
Count cardinal sets of similar objects. Learn that conjugation objects ass determine if the total is even
Determine whether a set of objects is even or odd
Identify whether the laid of given objects is even or odd. Learn that when objects in a set cannot be paired, then the enumerate is odd
Nam how addition pattern of +1 or +2 relates to even and odd
Study how relationship 'tween even and odd numbers happens by adding 1 or 2 to an even number
Square up whether a hidden number on a number job is even OR left over
Practice counting by 2s inside one-, two-, or three-digit numbers. Identify the value of consecutive numbers on a number line and whether they are even OR odd. Also, discover that zero is an even figure
Describe regular numbers as ones ending in 0, 2, 4, 6, or 8
Count away 2s to fill in a grid of equal numbers to learn that every last tied numbers end in 0, 2, 4, 6, Beaver State 8. Then practice gift even numbers; one-, two-, Beaver State three-digit numbers pool are accepted
Identify odd numbers As ones termination in 1, 3, 5, 7, surgery 9
Learn that all leftover numbers game end in 1, 3, 5, 7, operating room 9. Then practise entering odd numbers; united-, two-, or three-digit numbers are accepted
Identify 3-digit numbers as unexhausted operating theater even
Quality either all even or all inexact numbers out of a set of six 3-digit numbers game
Mental faculty 7. Trouble Solving with Length, Money, and Data
Topic A: Displaying Mensuration Data
Students create simple line plots supported weight and length measurements. They answer questions supported line plots, including how some, what measure, minimum, maximum, most common, least common, and total.
MODULE 8. Time, Shapes, and Fractions as Equal Parts of Shapes
Topic A: Composite Shapes and Divide Concepts
Working with triangles and squares, students rotate shapes to fill a pattern. They learn that the number of pieces in the whole are known as halves, thirds, fourths, and sixths based on the total telephone number.
Topic B: Halves, Thirds, and Fourths of Circles and Rectangles
Students repose on their knowledge of halves, thirds, and fourths to answer more complex questions about fractional parts of shapes. They split shapes into given fractions, identify the size of fractional parts, and tell how many parts make a whole.
Identify shapes that are split into halves
Given unrivaled operating room more than shapes, identify which are disunited into two equal parts, OR halves
Split shapes in fractional and complete the missing incomplete of shapes
Recognize that both shapes ass be split in fractional in other ways. Divide rectangles and hexagons into halves in different ways. Complete the missing half of a disposed human body
Identify shapes that are split into thirds and split shapes into thirds
Given cardinal Oregon more shapes, identify which are split into three equal parts, operating room thirds. Break shapes into thirds
Place shapes that are split into fourths and split shapes into fourths
Precondition ane or more shapes, identify which are split into four comparable parts, or thirds. Split shapes into fourths
Sort shapes that are split into halves, thirds, and fourths
Given a shape, identify whether IT is split into halves, thirds, surgery fourths
Identify parts of a whole in shapes split into halves, thrids, and fourths
Identify which fraction a mould is split into. Tell how many of a given divide are in a whole. Identify how galore more of a given fraction are needed to earn an incomplete cast whole
Topic C: Application of Fractions to Tell Time
Students begin with the basics of effective time - identifying the minute and minute hands on a time, tally around the proceedings on a clock, and telling time to the hour and one-half hour. They progress to telling time to 15 minutes and to 5 transactions, identifying midday and midnight, and using a.m. and p.m. Throughout, students use analog clocks, digital times, and lyric.
