Scoop a Ten!

Well we have started Module 2 from A Story of Units, from the New York State Common Core Curriculum. The first few lessons are on making a ten from 3 addends and finding a way to make a ten from 2 addends. My little friends were having some trouble with it, so I decided to create a center game they could spend extra time practicing.

Sticking with my ice cream theme that I've been using lately (don't worry - I'll get sick of it soon!!) I created "Scoop a Ten!"


This center game includes a poster with a poem, two sets of directions (one with just words, one with words and pictures), and a recording sheet. Simply print out, laminate, and place in a center. The kids can scoop up the ice cream, use three addends, find a ten, and solve an equation. 



Hope you enjoy scoopin' up a ten and solvin' some tasty problems!

Here are the Common Core State Standards associated with this center: 

CCSS.Math.Content.1.OA.B.4 Understand subtraction as an unknown-addend problem. For example, subtract 10 – 8 by finding the number that makes 10 when added to 8
CCSS.Math.Content.1.OA.C.6 Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
CCSS.Math.Content.1.OA.D.7 Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false. For example, which of the following equations are true and which are false? 6 = 6, 7 = 8 – 1, 5 + 2 = 2 + 5, 4 + 1 = 5 + 2.
CCSS.Math.Content.1.OA.D.8 Determine the unknown whole number in an addition or subtraction equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 + ? = 11, 5 = _ – 3, 6 + 6 = _.
