Estimating Throughout the Year

with Mrs. Opyr's Class

Throughout the year the grade ones in my class practise number by estimating and  counting an assortment of goodies that I provide in a jar. First the children are required to estimate and I note these on a chart and then we count to see the actual number. The numbers that are closest and furthest away are also identified by circling, underlining or crossing out. This is a good way to practise place value because when we count the items are grouped into piles of tens and leftover ones to make the counting easier. The grade two teacher extends this to place value in hundreds by using a larger jar with puzzle pieces, cube links, etc.

For this I used Chocolate jack o'lanterns at Halloween.

 

For this chart I used gold coins on St. Patrick's Day.

Other ideas include candy hearts or cinnamon hearts for Valentine's Day. For center activities I fill baby food jars with bread tabs, beads, beans, little plastic bears, etc.
