[divider] [/divider] Resources/Tasks to Help Your Child at Home:

Task: Choose a number and have your child count by ones starting at that number. Could use a 120s chart (https://goo.gl/NngTgc) or a number line (https://goo.gl/G7EHV8) to practice. This could also be done as you are counting pennies/other objects, driving, waiting in line, taking a walk, etc.

 

Number Line Interactive Online Tool – Use an interactive online number line to count by ones from any given number. https://goo.gl/VHuKWy

 

Task: Look for pictures of objects in the newspaper, magazines or books. Have your child practice counting how many there are by ones.  Then have them re-count to group by 10s and count on by ones.  (For example:  There are 23 apples on the page.  I made 2 groups of ten and counted on 3 ones.  So 10, 20, 21, 22, 23).
