### PRODUCT DESCRIPTION

Guide students through the Concrete, Pictorial, and Abstract stages of mathematical thinking with this hands-on Addition Bar Model Math Center! Help young mathematicians transition directly from concrete bar models using manipulatives, to pictorial bar model drawings, to the basic addition algorithms. This Concrete, Pictorial, and Abstract method is research-based and proven to be effective.

***************************************************************************

What does the math center include?

This math center includes 15 different worksheets of addition word problems within 10 that invite students to create bar models with Unifix cubes, draw the cubes, create number bonds with two parts and a whole, complete bar model drawings, and create and solve 2 different addition sentences that match the word problems. Also includes student center directions in kid-friendly "I can statements" and teacher directions following the gradual release of responsibility method.

***************************************************************************

How does it lead students through the Concrete, Pictorial, and Abstract Stages?

Concrete: Students will create the two parts of an addition story problem using 2 different colors of Unifix cubes.
Pictorial: Students will draw the cubes, complete the bar model, and solve for the whole on the dice number bond by counting the total dots on the dice.
Abstract: Students will create 2 different addition sentences that match the story problem and they will create the appropriate number bond with numerals for the two parts and the whole.

***************************************************************************

Why bar models?

This math center is great for introducing students to the bar model drawing process which is becoming more widely adopted in schools across the country. Bar model drawing is part of an effort to set students up for algebraic thinking in the higher grades. Each concrete bar model that your students create will match the bar model drawing on each page. In this way, it serves as a great visual introduction to the bar model drawing process!

***************************************************************************

How Can I Use Them In The Classroom?

They are designed to be used at math centers, however they can also be used as warm-ups at the beginning of math class or they can be used during independent or guided practice. The ‘Teacher Directions’ will carefully guide you through the gradual release of responsibility method when introducing this center to your students.

***************************************************************************

What Common Core is Covered?

1.0A.A.1: Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions.

1.OA.C.6: Add and subtract within 20, demonstrating fluency for addition and subtraction within 10.

2.0A.B.2: Fluently add and subtract within 20 using mental strategies.2 By end of Grade 2, know from memory all sums of two one-digit numbers.

***************************************************************************

What do I need to provide?

You will need to provide the Unifix cubes. If you do not have access to them, students can just move to the next stage which is drawing the cubes.
