How do you do extension and enrichment?
Beneath and Beyond the Standards: 5 Strategies for Enrichment and Extensions1) Teach Flexibility. Provide opportunities for students to build flexible and mental addition and subtraction strategies. 2) Encourage Pattern Identification. 3) Explore the World of Math. 4) Cultivate Joy. 5) Teach Depth not Breadth.
What are examples of enrichment activities?
Below are some examples of common enrichment activities:Work-related learning. These are activities that involve your students as active participants in learning about the world of work. Community participation. Personal development.
How do you provide enrichment in the classroom?
Encouraging children to do further research into a subject, for example by using books and websites, compiling presentations, or making posters. Setting tiered activities that take into account the different abilities within the class and allow more able students to work at a higher or wider level.
What can you change to balance an equation?
1: Balancing Equations. You cannot change subscripts in a chemical formula to balance a chemical equation; you can change only the coefficients. Changing subscripts changes the ratios of atoms in the molecule and the resulting chemical properties.
What three things does a balanced equation show you?
A chemical equation will tell you the formulas and symbols of the reactants and products. A chemical equation can show the physical state of a substance, whether it is a solid, liquid, gas, or in solution.
How do you know if an equation is balanced or unbalanced?
If each side of the equation has the same number of atoms of a given element, that element is balanced. If all elements are balanced, the equation is balanced.
What does a balanced equation look like?
A balanced chemical equation occurs when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side. In the products side, there are 1 nitrogen (N) atoms and 3 hydrogen (H) atoms. The number of the atoms is not balanced on both sides.
What happens if a chemical equation is not balanced?
Chemical reactions must be balanced, or in other words, must have the same number of various atoms in the products as in the reactants. If a chemical reaction is not balanced, no information about the relationship between products and reactants can be derived.

How do you balance equations with charges?
Balance charge. Add e- (electrons) to one side of each half-reaction to balance charge. You may need to multiply the electrons by the two half-reactions to get the charge to balance out. It’s fine to change coefficients as long as you change them on both sides of the equation.

Why do we need to balance a chemical equation?
1. An equation is balanced when the same number of each element is represented on the reactant and product sides. Equations must be balanced to accurately reflect the law of conservation of matter.
Which chemical equation is unbalanced?
Platinum is used as a catalyst. The equation is unbalanced because the number of hydrogen atoms is not the same on both sides of the equation. Barium chlorate (Ba(ClO3)2) breaks down to form barium chloride and oxygen. What is the balanced equation for this reaction?
Which is the most effective method of balancing armature?
The best way to minimize balance problems, is to minimize the initial unbalance which will need to be corrected. Unbalance in a small electric motor can be split into two categories, unbalance that is created BEFORE the armature is balanced, and unbalance that is created AFTER the armature is balance.
What are two reasons for balancing chemical equations?
Chemical equations are balanced in order to: 1) satisfy the Law of Conservation of Mass, and 2) establish the mole relationships needed for stoichiometric calculations. The Law of Conservation of Mass: The Law of Conservation of Mass states that mass cannot be created or destroyed.
Why do you need to balance a chemical equation?
Remember, chemical reactions follow the law of conservation of mass. Chemical equations show this conservation, or equality, in terms of atoms. You have to balance the equation to make the number of atoms equal on each side of an equation. …
Can all chemical equations be balanced?
A chemical equation represents the changes that occur during a chemical reaction. It has the general form: Reactants → Products. All chemical equations must be balanced. This means that there must be the same number of each type of atom on both sides of the arrow.
What does it mean when a chemical equation is balanced?
An equation is balanced when the same number of each element is represented on the reactant and product sides. Equations must be balanced to accurately reflect the law of conservation of matter.
