Number

3.N.1.1
number concepts to 1000
• counting:
 skipcounting by any number from any starting point, increasing and decreasing (i.e., forward and backward)
 skipcounting is related to multiplication
 investigating placevalue based counting patterns (e.g., counting by 10s, 100s; bridging over a century; noticing the role of zero as a placeholder 698, 699, 700, 701; noticing the predictability of our number system)
• Numbers to 1000 can be arranged and recognized:
 comparing and ordering numbers
 estimating large quantities
• place value:
 100s, 10s, and 1s
 understanding the relationship between digit places and their values, to 1000 (e.g., the digit 4 in 342 has the value of 40 or 4 tens)
 understanding the importance of 0 as a place holder (e.g., in the number 408, the zero indicates that there are 0 tens)

Computational Fluency

3.CF.2.1
addition and subtraction facts to 20 (emerging computational fluency)
• adding and subtracting of numbers to 20
• demonstrating fluency with math strategies for addition and subtraction (e.g., decomposing, making and bridging 10, related doubles, and commutative property)
• Addition and subtraction are related.

3.CF.2.2
addition and subtraction to 1000

3.CF.2.3
onestep addition and subtraction equations with an unknown number
• start unknown (e.g., n + 15 = 20 or □ + 15 + 20)
• change unknown ( e.g., 12 + n = 20 or 12 + □ = 20)
• result unknown (e.g., 6 + 13 = n or 6 + 13 = □)
• investigating even and odd numbers 
3.CF.2.4
fraction concepts
• Fractions are numbers that represent an amount or quantity.
• Fractions can represent parts of a region, set, or linear model.
• Fraction parts are equal shares or equalsized portions of a whole or unit.
• Provide opportunities to explore and create fractions with concrete materials.
• recording pictorial representations of fraction models and connecting to symbolic notation
• equal partitioning
• equal sharing, pole ratios as visual parts, medicine wheel, seasons

3.CF.2.5
multiplication and division concepts
• understanding concepts of multiplication (e.g., groups of, arrays, repeated addition)
• understanding concepts of division (e.g., sharing, grouping, repeated subtraction)
• Multiplication and division are related.
• Provide opportunities for concrete and pictorial representations of multiplication.
• Use games to develop opportunities for authentic practice of multiplication computations.
• looking for patterns in numbers, such as in a hundred chart, to further develop understanding of multiplication computation
• Connect multiplication to skipcounting.
• Connect multiplication to division and repeated addition.
• Memorization of facts is not intended for this level.
• fish drying on rack; sharing of food resources in First Peoples communities

3.CF.2.1

Patterning

3.P.3.1
increasing and decreasing patterns
• creating patterns using concrete, pictorial, and numerical representations
• representing increasing and decreasing patterns in multiple ways
• generalizing what makes the pattern increase or decrease (e.g., doubling, adding 2) 
3.P.3.2
pattern rules using words and numbers, based on concrete experiences
• from a concrete pattern, describing the pattern rule using words and numbers
• predictability in song rhythm and patterns
• Share examples of local First Peoples art with the class, and ask students to notice patterns in the artwork. 

3.P.3.1

Geometry & Measurement

3.GM.4.1
measurement, using standard units (linear, mass, and capacity)
• linear measurements, using standard units (e.g., centimetre, metre, kilometre)
• capacity measurements, using standard units (e.g., millilitre, litre)
• Introduce concepts of perimeter, area, and circumference (the distance around); use of formula and pi to calculate not intended — the focus is on the concepts.
• area measurement, using square units (standard and nonstandard)
• mass measurements, using standard units (e.g., gram, kilogram)
• estimation of measurements, using standard referents (e.g., If this cup holds 100 millilitres, about how much does this jug hold?)

3.GM.4.2
construction of 3D shapes
• identifying 3D objects according to the 2D shapes of the faces and the number of edges and vertices (e.g., construction of nets, skeletons)
• describing the attributes of 3D objects (e.g., faces, edges, vertices)
• identifying 3D objects by their mathematical terms (e.g., sphere, cube, prism, cone, cylinder)
• comparing 3D objects (e.g., How are rectangular prisms and cubes the same or different?)
• understanding the preservation of shape (e.g., the orientation of a shape will not change its properties)
• jingle dress bells, bentwood box, birch bark baskets, pithouses 

3.GM.4.3
time concepts
• understanding concepts of time (e.g., second, minute, hour, day, week, month, year)
• understanding the relationships between units of time
• Telling time is not expected at this level.
• estimating time, using environmental references and natural daily/seasonal cycles, temperatures based on weather systems, traditional calendar 

3.GM.4.1

Data & Probability

3.D.5.1
likelihood of simulated events, using comparative language
• using comparative language (e.g., certain, uncertain; more, less, or equally likely)
• developing an understanding of chance (e.g., tossing a coin creates a 5050 chance of landing a head or tail; drawing from a bag, using spinners, and rolling dice all simulate probability events)
• story: The Snowsnake Game (yukonedshowmeyourmath.wikispaces.com/file/view/The%20Snowsnake%20Game.pdf/203828506/The%20Snowsnake%20Game.pdf)
