2. Important Ideas in Kindergarten
Fall
Spring
-Count to 10
-Count objects 1:1 to 10
-Recognize numerals 0 to 10
-Count to 31 (forward and backward)
-Count objects 1:1 to 31
-Recognize numerals to 31
-Write numerals to 31
-order numbers from least to greatest
-Find 1 more and less than a number
-When counting a group of objects, the last number said is how many objects there are.
Big ideas: Connecting the numbers we write to quantities or things 3 =
The last number we say when we count represents the total 5 =
Recognizing the repeating pattern of the counting numbers:
0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22… .

Counting Collections:

5. Questions you can ask when counting collections
Can you give me the _____ ones?
How many ______ do you have?
Let’s count together!
Which has the most?
Which has the least?
Can you give me_____?
How many are left?
If I give you ____ more how many do you have?
Can you put them in (my hand, the bag) 1 by 1?
Can you double check?
Between this group and that group which has the most?
How many more do you need to have _____?
How many do you have again?

7. Important ideas in First Grade
Counting/Place Value
Adding/Subtracting
Other
Counting:
-Count to 120 (forward and backward)
-Read and write numbers to 120
-Skip count by 2s, 5s, 10s
Place Value
-Identify digits in the tens and ones place and their value
-Find 1 and 10 more/less than a number
-Compare and order numbers up to 120
-Doubles facts
-Make 10
-How fact families work
-Add 1, 2, 3
-Count on from higher number (don't have to start at 1)
Money/Time
-Name coins and values (penny, nickel, dime, quarter).
-Find the value of a group of coins (up to one dollar).
-Tell time to hour and half hour
Geometry
-Name and describe (sides and vertices) of basic shapes (2D: circle, triangle, square, rectangle, trapezoid, hexagon) (3D: cube, cone, cylinder, sphere, rectangular prism)
A ____ has _____ sides and vertices.
Big Ideas: Ten is the foundation of our number system. 8+2= 10 so 8+3= (8+2)+1
25 = 2 tens and 5 ones = =
1 dime= 10 cents, 2 nickels= 10 cents, 10 pennies= 10 cents, 10 dimes = 1 dollar

9. Important Ideas in Second Grade
Counting/Place Value
Adding/Subtracting
Other Co
-Count, read, and write numbers to 1,000
Place Value
-Identify digits in the hundreds, tens, and ones place and their value
-Find 1, 10, 100 more and less than a number
-Understand/know that 10 ones = 1 ten, 10 tens = 1 hundred, 10 hundreds = 1,000
-Round to the nearest 10 and 100
-Compare and order numbers up to 1,000
-1 digit numbers
-2 digit numbers
-Estimate sums and differences of 2 digit numbers
Money/Time
-Find the value of a group of coins.
-Determine different combinations of coins that equal a given amount.
-Tell time to the quarter hour
Geometry
-Name and describe (sides and vertices) of basic shapes (2D: circle, triangle, square, rectangle, trapezoid, hexagon) (3D: cube, cone, cylinder, sphere, rectangular prism)
A ____ has _____ sides and vertices.
Big Ideas: Ten is still very important, but now we learn that 10 tens = 100 and 10 hundreds = = 10 tens so 210= 21 tens
We have to pay attention to the value of the digits in the number.
432= 4 hundreds, 3 tens and 2 ones = ( ) + ( ) + (2 + 6)

Which one doesn’t belong:

12. Important Things to Remember…
-Knowing a concept in one language helps children learn it in another language
-Math in elementary school is where students learn the foundational for students conceptual understanding
-Speed is not as important as understanding why
- Thinking, noticing patterns and making connections is what is important for children in elementary school
