Pan Balance – Expressions 3-5, 6-8, 9-12 Using this interactive tool, you can practice arithmetic and algebraic skills, and investigate the important concept of equivalence. This lesson encourages students to explore another model of subtraction, the balance. This model leads naturally to recording with equations. Students use actual and virtual pan balances in their explorations and record the modeled subtraction facts and the related addition facts in equation form. Students use mathematical models to explore quantitative relationships. When presented with pictures of pan balances with one or more objects in each pan, they communicate relationships between the weights of the objects by comparing the balanced and unbalanced pans. Students will balance shapes on the pan balance applet to study equality, essential to understanding algebra. Equivalent relationships will be recognized when the pans balance, demonstrating the properties of. Name of Tech Tool: Illuminations - Pan Balance - Expressions Brief Description of Tech Tool: Students explore numeric expressions and balance using a scale and graphical representation. Younger students can compare whole and decimal values, while older students can explore graphical representation and changing x-values.

The Illuminations Pan Balance applet can be used as a mathematical model to represent and understand quantitative relationships, which supports one of the NCTM Algebra standards. The interactive point-plotting feature allows students to explore the graphic implications of changing the input or x-value of two different equations.

Search Results. Sort By: Finding the Balance. Pre-K-2, 6-8. This lesson encourages students to explore another model of subtraction, the balance. Students will use real and virtual balances. Students also explore recording the modeled subtraction facts in equation form. Pan Balance – Expressions. 3-5, 6-8, 9-12. Using this. Solve simple linear equations using a balance beam representation. Como usar a balança. Coloca pesos em cada um dos pratos da balança, arrastando as formas, de maneira que a balança fique equilibrada. Se quiseres ver o número de peças, pressiona Count Items. Scales Problems 1. Solve how much each geometric shape "weighs". You can use either pounds or kilograms. This is a pan balance or scales. Things go into the two "pans", and the heavier pan will go down, like in a seesaw. If the two things weigh the same, the balance stays balanced. a. The square weighs _____ b. The square weighs _____ c. In Pan Balance-Shapes, students can explore equality which is an important component of algebra. Students put shapes on a balance to try to find equivalent relationships. The applet records what shapes are on the pan when an equivalent relationship is found.
