Correctly count and represent the number of objects in a set using numerals.
-
1.M1N1.c
Compare small sets using the terms greater than, less than, and equal to (>, <, =).
-
1.M1N1.d
Understand the magnitude and order of numbers up to 100 by making ordered sequences and representing them on a number line.
-
1.M1N1.e

-
1.M1N1.f
Identify bills ($1, $5, $10, $20) by name and value and exchange equivalent quantities by making fair trades involving combinations of bills and count out a combination of bills needed to purchase items less than twenty dollars.
-
1.M1N2
Understand place value notation for the numbers between 1 and 100. (Discussions may allude to 3-digit numbers to assist in understanding place value.)
-
1.M1N2.a
Determine to which multiple of ten a given number is nearest using tools such as a sequential number line or hundreds chart to assist in estimating
-
1.M1N2.b
Represent collections of less than 30 objects with 2-digit numbers and understand the meaning of place value.
-
1.M1N2.c
Decompose numbers between 11 and 19 as one ten and the appropriate number of ones.
-
1.M1N3
Students will add and subtract numbers less than 100 as well as understand and use the inverse relationship between addition and subtraction.
-
1.M1N3.a
Identify one more than, one less than, 10 more than, and 10 less than a given number.
-
1.M1N3.b
Skip-count by 2's, 5's, and 10's forward and backwards - to and from numbers up to 100.
-
1.M1N3.c
Compose/decompose numbers up to 10 --"break numbers apart", e.g., 8 is represented as 4 + 4, 3 + 5, 5 + 2 + 1, and 10-2.
-
1.M1N3.d
Understand a variety of situations to which subtraction may apply: taking away from a set, comparing two sets, and determining how many more or how many less.
-
1.M1N3.e
Understand addition and subtraction number combinations using strategies such as counting on, counting back, doubles and making tens.
-
1.M1N3.f
Know the single-digit addition facts to 18 and corresponding subtraction facts with understanding and fluency. (Use strategies such as relating to facts already known, applying the commutative property, and grouping facts into families.)
-
1.M1N3.g
Apply addition and subtraction to 2 digit numbers without regrouping (e.g.15 + 4, 80 - 60, 56 + 10, 100 - 30, 52 + 5).
-
1.M1N3.h
Solve and create word problems involving addition and subtraction to 100 without regrouping. Use words, pictures and concrete models to interpret story problems and reflect the combining of sets as addition and taking away or comparing elements of sets as subtraction.
-
1.M1N4
Students will count collections of up to 100 objects by dividing them into equal parts and represent the results using words, pictures, or diagrams.
-
1.M1N4.a
Use informal strategies to share objects equally between two to five people.
-
1.M1N4.b
Build number patterns, including concepts of even and odd, using various concrete representations. (Examples of concrete representations include a hundreds chart, ten grid frame, place value chart, number line, counters, or other objects.).
-
1.M1N4.c
Identify, label and relate fractions (halves, fourths) as equal parts of a whole using pictures and models.

1.M1M
Measurement
|
-
1.M1M1
Students will compare and/or order the length, weight, or capacity of two or more objects by using direct comparison or a nonstandard unit.
-
1.M1M1.a
Directly compare length, weight, and capacity of concrete objects.
-
1.M1M1.b
Estimate and measure using a non-standard unit that is smaller than the object to be measured.
-
1.M1M1.c
Measure with a tool by creating a "ruled" stick, tape, or container by marking off ten segments of the repeated single unit.
-
1.M1M2
Students will develop an understanding of the measurement of time.
-
1.M1M2.a
Tell time to the nearest hour and half hour and understand the movement of the minute hand and how it relates to the hour hand.
