The Importance of
Coherence in Math
Coherence
Math should make sense
Math should make sense
• Within a grade level
• Across many grade levels
A progression of learning
Coherence supports focus
Use supporting material to teach major content
Coherence WITHIN a grade level
The standards within a grade level strategically allow:
Instruction that reinforces major content and utilizes
supporting standards
Important to remember:
Meaningful introduction to topics so that skills
complement one another
Coherence WITHIN a grade level
Draw a scaled picture graph
and a scaled bar graph to
represent a data set with
several categories. Solve oneand two- step “how many
more” and “how many less”
problems using information
presented in scaled bar graphs.
3.MD.3
Use addition and subtraction within 100 to solve word
problems involving lengths that are given in the same
units, e.g., by using drawings (such as drawings of rulers)
and equations with a symbol for the unknown number
to represent the problem.
2.MD.5
Geometric measurement: understand concepts of
area and relate area to multiplication and addition.
3.MD.3rd cluster
Make a line plot to display a data set of measurements in fractions of a unit ( ½, ¼, 1/8).
Solve problems involving addition and subtraction of fractions by using information
presented in line plots.
4.MD.4
Coherence ACROSS grade levels
Students apply skills from previous grade levels to learn
new topics in their current grade level
Meaningful math progressions reflect this, building
knowledge across the grade levels
Coherence ACROSS grade levels
One of several staircases to algebra
designed in the OA domain.
Coherence ACROSS grade levels
CCSS
Grade 4
4.NF.4. Apply and extend previous understandings of multiplication to
multiply a fraction by a whole number.
5.NF.4. Apply and extend previous understandings of multiplication to
multiply a fraction or whole number by a fraction.
Grade 5
5.NF.7. Apply and extend previous understandings of division to divide
unit fractions by whole numbers and whole numbers by unit fractions.
6.NS. Apply and extend previous understandings of multiplication and
division to divide fractions by fractions.
Grade 6
6.NS.1. Interpret and compute quotients of fractions, and solve word
problems involving division of fractions by fractions, e.g., by using visual
fraction models and equations to represent the problem.

counting)
Number naming

Sequencing numbers
Ordering numbers
Sequencing vs. Ordering
Sequencing: children rely on an auditory and visual
structure to put a set of numbers in ascending or
descending order (by 1s,2s, 5s, 10s)
PREREQUISITE FOR ORDERING, ROUNDING, OR ESTIMATING NUMBERS
Ordering numbers: placing a set of numbers in ascending
or descending order that do not have a visual, imaginary,
or auditory pattern; Ex: 17, 23, 34

SUBTRACTION
Learning Framework in Number
(SEAL) STAGES OF EARLY ARITHMETIC LEARNING
Stage
0
Emergent
Child is learning the counting sequence and developing one-to-one correspondence in counting,
but cannot yet count visible items accurately. (disorganized count, skips some, counts some twice,
etc.)
Stage
1
Perceptual
Child can count visible items but can only deal with adding visible quantities, not screened items.
Child may solve simple screened problems in finger range by re-presenting with fingers and counting
forward from 1 three times to solve. (Watch the fingers)
Stage
2
Figurative
Child can deal with screened addition by using a number sequence logic, counting forward from 1.
(Early 2 – fingers/touches, Mid 2 – spatial patterns, High 2 – mental counts)
Stage
3
Counting on
Stage
4
Intermediate #
Stage
5
Stage
6
Child solves addition by counting on, subtraction by counting back and missing addend problems by
counting up or counting back. They understand cardinality of number and think of numbers as
composite groups as well as units
Child uses most efficient counting strategy to solve +/- problems. (counting up to, counting back
from, counting back to.) Understands part/whole
Facile #
Child solves addition/subtraction problems by choosing from a full range of non-counting by one
strategies including doubles, think ten, partitioning, using known facts, etc. (A rule of thumb is that the
child must show evidence of at least three different strategies.)
Advanced #
Child extends and applies knowledge of addition and subtraction to solve a range of tasks, including
multi-digit addition and subtraction, by focusing in on the relationships between numbers and
operations and generalized number sequences/relations. (commutativity, associativity, relationship
between +/-, growing number patterns, etc)
Level 1
Level 2
Level 3
Initial Concept
Child doesn’t see ten as a composite unit. Focuses on ten individual
items that makeup the ten. On +/- tasks involving tens and ones,
child counts forward or backward by ones.
Intermediate
Concept of Ten
Ten is seen as a unit comprised of ten ones. Child is dependent on
representations of units of ten (Craft sticks bundles, dot strips) The
child can perform = - tasks involving tens and ones when these tasks
are presented with materials, (Could add 10s and 1s, such as 4, 14,
24, 34, etc. if dot strips and dots/bundles, base ten materials)
Concept of Ten
Child can mentally solve +/- tasks using knowledge of tens and ones
(additive property, place value property without using materials or
representations of materials. 9penil/paper, “visual” chalkboard)

Grouping
Cannot describe or make equal groups or shares
Uses perceptual counting (by ones) to establish the numerosity of a collection of
equal groups to share items into groups of equal size or to share items into an
equal number of groups.
Level

Initial Grouping
Level

Perceptual
Counting in

Uses a multiplicative counting strategy (Skip counting) to count visible items
arranged in equal groups, to share items into groups of equal size of to share items

Composite
Uses multiplicative counting strategy (skip counting0 to cunt items arranged in
equal groups where items are unseen (but group markers are shown)
Level
4
Level
5
Counts composite units using repeated addition or subtraction where items are
Repeated abstractunseen. Uses the composite unit the specified number of times. (4 x 6 is 4 + 4 is 8
Composite
and another 4 +4 = 8. 8 + 8 = 16, 16 + 4 = 20 ad 20 + 4 = 24.
Grouping
Multiplication as
Operations
Can recall and derive many facts for multiplication and division ( 8 x 6 = 48, 7 x 9 is
like 7 x 10 - .
Array
Visual representation of rows and columns for multiplication computation
4 x 3 = 12
Array Game
Pairs of students receive a grid, 2 dice and 2 different colored
crayons/markers
Each child rolls the dice and then creates an array that matches
the number pair rolled
Goal: fill the grid
If a child’s array does not fit in the remaining space on the grid
they must pass and receive a strike. 3 strikes and the child is out
Area Model: 3rd, 4th, 5th
Pictorial representation of the Partial
products method
Capitalizes on student’s understanding
of place value
After sufficient practice with partial
products, the standard algorithm makes
much more sense

entire garden?
