Grade-Two Power Standards
Math
- M(N&O)–2–1 Demonstrates conceptual understanding of rational numbers with
respect to:
- whole numbers from 0 to 199 using place value,
- by applying the concepts of equivalency in
composing or decomposing numbers (e.g., 34 = 17 + 17; 34 = 29 + 5);
- and in expanded notation (e.g., 141 = 1 hundred
+ 4 tens + 1 one or 141 = 100 + 40 + 1) using models, explanations, or
other representations;
- and positive fractional numbers (benchmark fractions: a/2, a/3,
or a/4, where a is a whole number greater than 0 and less
than or equal to the denominator) as a part to whole relationship in area
and set models where the denominator is equal to the number of parts in
the whole using models, explanations, or
other representations.
- M(N&O)–2–2 Demonstrates
understanding of the relative magnitude of numbers from 0 to 199 by
- ordering whole numbers; by
- comparing whole numbers to each other or to
benchmark whole numbers (10, 25, 50, 75, 100, 125, 150, or 175); by
- demonstrating an understanding of the relation of inequality
when comparing whole numbers by using “1 more”, “1 less”, “10 more”, “10
less”, “100 more”, or “100 less”; or by connecting number words and
numerals to the quantities they represent using models, number lines, or
explanations.
- M(N&O)–2–3 Demonstrates
conceptual understanding of mathematical operations involving addition and subtraction of whole
numbers by
- roficiency - title (le (Local)solving problems involving
- joining actions,
- separating actions,
- part-part whole
relationships,
- comparison situations;
- addition of multiple one-digit
whole numbers.

(See Appendix A for definitions)
- M(N&O)–2–5 Demonstrates understanding of monetary value by
- adding
coins together to a value no greater than $1.99
- representing
the result in dollar notation;
- making
change from $1.00 or less,
- recognizing equivalent coin representations of the
same value (values up to $1.99).
- M(G&M)–2–6 Demonstrates conceptual understanding of
perimeter and area by
using models or manipulatives to surround and cover polygons.
- M(G&M)–2–7 Measures and uses units
of measures appropriately and consistently, and makes conversions within
systems when solving problems across
the content strands.
(see appendex B)
- M(F&A)–2–4 Demonstrates
conceptual understanding of equality
by finding the value that will make an open sentence true
(e.g.,
). (limited
to one operation and limited to use addition or subtraction)
8.
M(DSP)–2–1
Interprets a given representation (pictographs with one-to-one
correspondence, line plots, tally charts, or tables) to
a.
answer
questions related to the data,
b.
to analyze the data to formulate conclusions.
(IMPORTANT: Analyzes data consistent with concepts and skills in M(DSP)–2–2[more/less/same.)
- M(DSP)–2–4
Uses counting techniques to solve problems involving combinations using a variety of strategies (e.g., student diagrams, organized
lists, tables, tree diagrams, orsc
others); (e.g., How many ways can you make 50 cents using nickels, dimes,
and quarters?)
