Modeling Numbers
Use any objects to build the numbers to model addition and subtraction facts.
Model with Base Ten Blocks
Use base ten blocks to model. Have students practice trading ten ones cubes for one tens stick and vice versa.

- Linking cubes in different colors
Modeling with Students
Call groups of students to the front. Make related fact sentences using the students. (Call three boys and two girls. 3 +2 = 5, 2 + 3 = 5, 5 – 3 = 2,5-2 =3 or four students with sweatshirts and one with a t-shirt etc..)

Modeling Numbers
Use any objects to build the numbers to model addition and subtraction facts. Have students practice modeling number sentences with information found in word problems and create their own word problems.
Model with Base Ten Blocks
Use base ten blocks to model. Have students practice trading ten ones cubes for one tens stick and vice versa.

Focus: Counting
SOL 2.4-The student will
a) count forward by twos, fives, and tens to 100, starting at various multiples 2,5, or 10;
b)count backwards by tens from 100; and
c)recognize even and odd numbers / Digit, sequence, skip count, two, five, ten, even, odd /

Base Ten Blocks
When skip counting forward and backwards by ten have students practice by moving a tens stick each time they say a ten.
Modeling Numbers to Determine Even or Odd
Use any objects to build the number to determine if the number is even or odd. Have students group the objects in pairs of two.

value of each digit in a three-digit
numeral, using numeration models;
b) round two-digit numbers to the
nearest ten; and
c) compare two whole numbers
between 0 and 999, using symbols
(>, <, or =) and words (greater than,
