1-1 Tens and Ones:  I can count, read, and write tens and ones.

Vocabulary:  Ones:  a place value of a number.  Example:  In the number 23, the 3 is in the ones place.  This number has 3 ones.  Tens:  a place value of a number.  Example:  In the number 23, the 2 is in the tens place.  This number has 2 tens.

1-2 Place Value to 100:  I can use models of tens and ones to show numbers to 100.

Vocabulary:  Digit:  a symbol use to write numbers (there are 0, 1, 2, 3, 4, 5, 6, 7, 8, and, 9).  Place Value:  value given to a digit by its place in a number.      For example, in the number 46, the 4 is in the tens place… so it isn’t just a 4… it is 4 tens which means it has the value of 40.

Is equal to =:  both numbers have the same value on either side of the symbol.
