South Dakota Grade 1 math is where students build addition and subtraction fluency, place-value understanding, early measurement, shapes, and clear math explanations. This South Dakota Content Standards guide gives South Dakota families and educators a parent-friendly and teacher-friendly guide to the skills behind the assessment: 22 student-friendly expectations across 4 math strands, with emphasis on operations, equations, patterns, and problem solving, place value, rounding, comparing numbers, and multi-digit computation, measurement, time, data, area, perimeter, and graphing. Whether the next checkpoint is classroom progress, intervention, homeschool planning, or SBAC review, the best preparation uses short mixed-review sessions, quick model drawing, and one written explanation at a time.
Use this South Dakota Grade 1 page for lesson planning, homeschool pacing, and skill-by-skill progress checks. The wording, examples, and practice notes are tailored to South Dakota Content Standards, so the page works as a grade-specific planning tool rather than a copied standards list.

South Dakota Grade 1 Math Standards Overview
For South Dakota, Grade 1 is a turning point: students build addition and subtraction fluency, place-value understanding, early measurement, shapes, and clear math explanations. This overview organizes South Dakota Content Standards into plain-language strands so you can quickly identify what to teach, review, or reteach.
Learning reference group 1
Example learning reference: Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes. Read the individual expectations below and check the current classroom target.
Learning reference group 2
Example learning reference: Order three objects by length; compare the lengths of two objects indirectly by using a third object. Read the individual expectations below and check the current classroom target.
Learning reference group 3
Example learning reference: In the range of 0 – 120. Read the individual expectations below and check the current classroom target.
Learning reference group 4
Example learning reference: Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions,. Read the individual expectations below and check the current classroom target.
Grade 1 SBAC Practice Plan
A useful South Dakota Grade 1 plan should not race through all 22 expectations at once. Start with a few classroom targets, rotate in quick review, and ask students to explain how they know. Begin with an expectation the student can explain partly, then revisit earlier skills as understanding grows.
For South Dakota Grade 1 students, a strong weekly rhythm is simple: one fluency warm-up, one visual model, one word problem, one written explanation, and one quick check tied back to South Dakota Content Standards. That routine keeps SBAC practice connected to real Grade 1 standards instead of random worksheets.
South Dakota Grade 1 Math Learning References
The codes below follow the South Dakota Grade 1 source standards structure. The wording is intentionally rewritten in original, family-friendly language for learning and planning.
Learning reference group 1
Read the learning reference, choose a model or text that makes the idea clear, and compare the code with your current classroom target.
Use these Grade 1 expectations as learning references. Common Core-style codes refer to the Common Core standards; they do not certify a complete match to South Dakota’s current curriculum. State-specific references also need to be checked against the current official document. Follow your teacher’s assigned targets when wording, codes, or grade placement differ.
| Code | Learning reference |
|---|---|
| 1.G.1 | Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes |
| 1.G.2 | Compose and identify regular and irregular two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) and compose three-dimensional shapes (cubes, spheres, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape |
| 1.G.3 | Partition circles and rectangles into two and four equal shares, describe the shares using the words halves, fourths, and quarters, and use the phrases half of, fourth of, and quarter of. Describe the whole as two of, or four of the shares. Understand for these examples that decomposing into more equal shares creates smaller shares |
Learning reference group 2
Read the learning reference, choose a model or text that makes the idea clear, and compare the code with your current classroom target.
| Code | Learning reference |
|---|---|
| 1.MD.1 | Order three objects by length; compare the lengths of two objects indirectly by using a third object |
| 1.MD.2 | Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps |
| 1.MD.3 | Tell and write time in hours and half-hours using analog and digital clocks |
| 1.MD.4 | Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another |
| 1.MD.5 | Identify nickels and understand that five pennies can be thought of as a nickel. Identify dimes and understand ten pennies can be thought of as a dime. Count the value of a set of coins comprised of pennies, nickels, and dimes |
Learning reference group 3
Read the learning reference, choose a model or text that makes the idea clear, and compare the code with your current classroom target.
| Code | Learning reference |
|---|---|
| 1.NBT.1 | In the range of 0 – 120 |
| 1.NBT.2 | Understand that the two digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases |
| 1.NBT.3 | Compare two two-digit numbers based on meanings of the tens and ones digits, recording the results of comparisons with the symbols <, =, and > |
| 1.NBT.4 | Add and subtract within 100 |
| 1.NBT.5 | Given a two-digit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used |
| 1.NBT.6 | Subtract multiples of 10 in the range 10-90 from multiples of 10 in the range 10-90 (positive or zero differences), using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used |
Learning reference group 4
Read the learning reference, choose a model or text that makes the idea clear, and compare the code with your current classroom target.
| Code | Learning reference |
|---|---|
| 1.OA.1 | Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, |
| 1.OA.2 | Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20, |
| 1.OA.3 | Apply commutative, associative, and additive identity properties of operations as strategies to add |
| 1.OA.4 | Understand subtraction as an unknown-addend problem |
| 1.OA.5 | Understand counting on as addition and counting back as subtraction |
| 1.OA.6 | Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. |
| 1.OA.7 | Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false |
| 1.OA.8 | Determine the unknown whole number in an addition or subtraction equation relating to three whole numbers |
