Part of: [Wyoming: Mathematics](https://ai.page/roadmap/wy.md)

Goal: Wyoming academic standards: Mathematics, Grade 2

## 1. Geometry · Partition rectangles into two, three, or four equal shares by:

- [Halves & Quarters of Shapes](https://ai.page/c/halves-and-quarters-of-shapes/index.md): Partition circles and rectangles into two and four equal shares and describe them using the words halves, fourths, and quarters

## 2. Geometry · Partition circles and rectangles into two, three, or four equal shares by:

- [Splitting shapes into equal parts (age 7+)](https://ai.page/c/splitting-shapes-into-equal-parts-age-7/index.md): Partition circles and rectangles into two, three, or four equal shares; describe shares as halves, thirds, and fourths; recognise that equal shares of identical wholes need not have the same shape

## 3. Measurement And Data · Use a number line diagram with equally spaced points to:

- [Numbers on a number line](https://ai.page/c/numbers-on-a-number-line/index.md): Represent whole numbers as lengths on a number line and represent sums and differences within 100 on a number line diagram

## 4. Number And Operations In Base Ten · Add and subtract within 1000, using concrete models or drawings and strategies based on place value, properties of addition, and/or the relationship between additio

- [Addition and subtraction within 1000](https://ai.page/c/addition-and-subtraction-within-1000/index.md): Add and subtract within 1000 using concrete models, drawings, and strategies based on place value; understand composing and decomposing tens and hundreds

## 5. Number And Operations In Base Ten · Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones; and demonstrate that:

- [A Hundred Is Ten Tens](https://ai.page/c/a-hundred-is-ten-tens/index.md): Understand that 100 can be thought of as a bundle of ten tens — called a 'hundred'
- [The three digits of a three-digit number](https://ai.page/c/the-three-digits-of-a-three-digit-number/index.md): Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones

## 6. Number And Operations In Base Ten · Understand that the four digits of a four-digit number represent amounts of thousands, hundreds, tens, and ones; and demonstrate that:

- [The two digits of a two-digit number](https://ai.page/c/the-two-digits-of-a-two-digit-number/index.md): Understand that the two digits of a two-digit number represent amounts of tens and ones
- [Place value of each digit](https://ai.page/c/place-value-of-each-digit/index.md): Recognise the place value of each digit in a four-digit number (thousands, hundreds, tens, and ones)

## 7. Operations And Algebraic Thinking · Determine whether a group (up to 20) has an odd or even number of objects (i.e. by pairing objects or counting them by 2s).

- [Odd or Even](https://ai.page/c/odd-or-even/index.md): Determine whether a group of objects (up to 20) has an odd or even number of members
