Description

EAI® Education Bar Models make modeling mathematical concepts a hands-on, logical experience for students. Each set of Bar Models features 84 vibrantly colored dry-erase pieces in 12 different lengths, ranging from 1-12cm. Each set is packed in a zippered vinyl pouch for easy storage.

Bar Models give students the ability to build the concrete structure of a problem, transfer to a Bar Model drawing of the problem (also referred to as a Strip Diagram), then migrate to the abstract, or algorithm, to solve the problem. The flat, dry-erase writing surface on each piece allows students to "write what they are modeling" directly on the Bar Model with a dry-erase marker to assist with the visual representation of a problem, then assign values to the other Bar Model tiles using the relationship of size among the pieces.

For elementary learners, Bar Models provide a hands-on of model for flexible thinking in representing all the operational problems which include joining, separating, or comparing numbers. Bar Models can be used to show missing addends, the commutative property, equivalence, writing number sentences, and more. For upper elementary and middle school learners, Bar Models can be expanded to demonstrate student thinking involving factors, multiples, fractions, ratios, proportions, rates, algebraic reasoning, and more. This item includes 30 sets of 84 pieces in a storage tub.

The interactive color bar graph tool offers a great way to model addition, subtraction, multiplication, division, and fractions. The graph color bars may also be used as an interactive tape diagram tool. Additionally, you may use the bar graph tool to show data.

To use the online graph color bar tool, drag bars onto the graph paper. Remove bars by dragging them off the screen.

Here are some possible ways to use the interactive bar graph tool in your classroom:

Ask students to drag the ten bar onto the graph paper. Then, ask students to show as many combinations to form ten as possible below.

Ask students to represent an addition or subtraction problem using the bars. For example, they can show 2 + 6 = 8 by dragging the two and the six onto the screen side by side. Then, they can place the 8 above it.

Ask students to represent a multiplication or division problem using the bars. For example, students can show 3 x 3 = 9 or 9 ÷ 3 = 3.

Ask students to represent teen numbers using the bars.

Ask students to represent a fraction using the bars. For example, you might ask them to represent 1/4 or 1/2 of the number 4 using the bars.

Show students a data set and ask them to represent it on the graph paper.

"We got our order on Wednesday. It was perfectly packed on a huge pallet wrapped in cellophane. Each teacher checked over their individually labelled boxes and everything was perfect! I absolutely LOVED ordering this way...not only easier for me, but it made the teachers feel as if they were opening a gift meant just for them. Some said it felt like Christmas!"
