23 standards

Operations and Algebraic Thinking

9 standards
1.1
Solve story problems within 20 that add to, take from, put together, take apart or compare, using objects, drawings or equations with a box for the unknown.
1.2
Solve story problems that add three whole numbers totaling 20 or less, showing the problem with objects, a drawing or an equation with a box for the missing number.
1.3
Use the rules of adding as shortcuts when adding and subtracting, like knowing 3 + 8 equals 8 + 3 or grouping 2 + 6 + 4 as 2 + 10.
1.4
Explain how a subtraction can be solved as a missing addend, like finding 10 minus 8 by asking what number added to 8 makes 10.
1.5
Connect counting to adding and subtracting, like counting on 2 from 5 to find 5 + 2, or counting back to take away.
1.6
Add and subtract within 20, knowing facts to 10 fluently by counting on, making ten, breaking a number apart, using related facts or easier known sums.
1.7
Explain that the equal sign means both sides have the same value, and decide whether addition and subtraction equations like 6 = 7 - 1 are true or false.
1.8
Find the missing whole number in any position of an addition or subtraction equation with three numbers, like what plus 8 makes 11.
1.9
Copy, continue and make up patterns and number sequences with different materials, like stringing beads or counting by 2s.

Operations with Numbers: Base Ten

6 standards
1.10
Count forward and back by ones from any number below 120, read and write numerals up to 120, and write the number for a set of up to 120 objects.
1.11
Explain that a two-digit number shows tens and ones, seeing ten ones as one ten, 11 to 19 as a ten plus ones, and 10, 20 and so on to 90 as whole tens.
1.12
Compare two two-digit numbers by their tens and ones, recording the result with >, = or < and saying it as greater than, equal to or less than.
1.13
Add within 100 with models or drawings and place value, like 46 + 7 or 46 + 30, adding tens to tens and ones to ones, regrouping as needed, and explaining the written steps.
1.14
Find 10 more or 10 less than any two-digit number mentally, without counting, and explain the thinking, like 54 becomes 64 or 44.
1.15
Subtract a multiple of 10 from another between 10 and 90, like 70 - 30, using models, drawings and place value, then link it to a written method and explain.

Data Analysis

1 standard
1.16
Sort, show and read data in up to three groups on Venn diagrams, pictographs or yes-no charts, finding each group's count, the total, and how many more or fewer.

Measurement

4 standards
1.17
Put three objects in order from shortest to longest, and compare two objects by measuring each against a third one.
Common Core 1.MD.1
1.18
Measure an object's length with nonstandard units laid end to end with no gaps or overlaps, giving a whole number, like 7 paper clips long.
1.19
Tell and write time to the hour and half hour on both analog and digital clocks, like 3:00 and 3:30.
1.20
Name a penny and a dime on sight and tell what each is worth, 1 cent and 10 cents.

Geometry

3 standards
1.21
Build and draw shapes from their defining features, telling which features define a shape, like three sides, and which do not, like color or size.
1.22
Put shapes together, like two triangles into a square or cubes into a tower, to make a new shape, and build again from the new shape.
Common Core 1.G.2
1.23
Split circles and rectangles into two or four equal parts named halves, fourths or quarters, see the whole as all the parts, and see more parts means smaller parts.
