[|Early Number Sense powerpoint]

Count sets of objects accurately. Make sets with a given number. Compare sets of objects using one to one correspondence (same number, more than, less than). Make sets with more/less/same. Count forward from a given number (using counters if needed; real counting on to tell all). Know one more, one less. Count backward from a given number (count up and back; count up and back on a calculator)

Count objects by twos. Know two more, two less. Compare numbers. Recognize patterns on dot plates, five-frame cards, ten-frame cards. Use five-frame and ten-frame cards to compose numbers to five and ten. Decompose small sets of numbers (show five in hand, remove two, ask “how many are in my other hand?”) Read and write numbers to 30. Count by fives and tens, using grouped objects as needed.

Read and write numbers to 110. Count backward by 1s starting from any number between 1 and 100. <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; margin: 0in 0in 4pt;">Compare two numbers to 110. Order small sets of small numbers. <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; margin: 0in 0in 4pt;">Skip counting: Count to 110 by 1s, 2s, 5s and 10s, starting from any number. <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; margin: 0in 0in 4pt;">Place value: <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; margin: 0in 0in 4pt 0.25in; text-indent: -9pt;">Count to 500 by 10s and 100s. <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; margin: 0in 0in 4pt 0.25in; text-indent: -9pt;">Identify one more than, one less than, 10 more than and 10 less than for any number up to 100. <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; margin: 0in 0in 4pt 0.25in; text-indent: -9pt;">Compose and decompose numbers through 30, including using bundles of tens and units, e.g., recognize 24 as 2 tens and 4 ones, 10 and 10 and 4, 20 and 4, and 24 ones. <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; margin: 0in 0in 4pt;">Understand that a number to the right of another number on the number line is bigger and that a number to the left is smaller. <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; margin: 0in 0in 4pt;">List number facts (partners inside of numbers) for 2 through 10; e.g., 8 = 7 + 1 = 6 + 2 = 5 + 3 = 4 + 4; 10 = 8 + 2 = 2 + 8. <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; margin: 0in 0in 0pt;">Compare two or more sets in terms of the difference in number of elements.
