Grade 1

**To make tally marks:**tally one, two, three, four, diagonal to make a group of 5; tally 6, seven, eight, nine, diagonal to make a group of 10, etc.**To add two numbers:**start with the larger number and count on 3 + 5 --- say “5″ then count on 3 more – 6, 7, 8. The answer is 8.**When we count coins:**arrange them with the largest value coin first – so, put all the dimes first, then the nickels, and then the pennies.**Telling time:**the hour hand is short the minute hand is long – we count the minutes by 5s starting at the 1 and ending at the long hand.Grade 2

Please practice basic 0-10 addition/subtraction and doubles facts frequently at home. The goal is to become AUTOMATIC and be able to find the answer quickly. Also when talking about numbers please refer to their place values-- ones, tens, hundreds, thousands, etc. Other strategies that will be covered later will be horizontal partial sums, vertical partial sums, and empty number line. These will be updated when the skills are being taught in class.

Expanded Notation: Breaking apart the place values

Ex.) 45= 40 + 5

Ex.) 187 = 100 + 80 + 7

Grade 4/5

The strategies that are used in 4/5th grade are horizontal partial sums, traditional addition, empty number line, horizontal partial differences, circles and stars, Partial Products, and Partial Quotients. The strategies will be posted as they are introduced in class. Your child will recognize which strategy they use since every child may use a differing strategy.

1.) Look at the largest place value

2.) Write whole number based on largest or smallest

-Cross out used number/s

3.) Continue until you find common numbers

4.) Look at the second largest place value

5.) Write whole number based on largest or smallest

-Cross out used number/s

6.) Continue until all numbers are written down

Ex.)(round to closest 10/100) ______ 63 ________

1.) ? What ten/hundred are you at ?

Write that number on the left line

2.) ? What is the next ten/hundred ?

Write that number on the right line

3.)

Circle 60.

3.)

Circle 200.

Ex.) (round to closest 10) _______ 126 ________

1.) Circle the tens and ones place

2.) All numbers before the tens and ones need to be written down on both lines. (_

3.) ? What ten are you at ?

Write that number on the left line behind the hundred ( _

2.) ? What is the next ten/hundred ?

Write that number on the right line ( _

3.) ? Is 126 closer to 120 or 130 ?

Circle 130.
