situation and solution equations for multiplication and division

Ask them to solve the equation. If the cards are not a match, the next student takes a turn.Students each draw 5 cards.

problems with one missing number. In the next example, the variable is multiplied by 5, so we will divide both sides by 5 to ‘undo’ the multiplication.If you multiply both sides of an equation by the same number, you still have equality.Since the product of a number and its reciprocal is 1, our strategy will be to isolate.In the next example, all the variable terms are on the right side of the equation.

For this reason, the product or answer of the multiplication problem is the dividend or first number in the division problems.When students are finished working, ask individual students to write the fact families from the back page on the board. While this would work, multiplying by the reciprocal requires fewer steps.Many equations start out more complicated than the ones we’ve just solved. Remember, the left side of the workspace must equal the right side, but the counters on the left side are “hidden” in the envelopes. Activity ( M-3-5-2_Wipe Out! }{=} -9\; \checkmark \end{split}$$,$$\begin{split} \dfrac{-3n}{\textcolor{red}{-3}} &= \dfrac{21}{\textcolor{red}{-3}} \\ n &= -7 \end{split}$$,$$\begin{split} −3(n − 2) − 6 &= 21 \\ -3(\textcolor{red}{-7} - 2) - 6 &\stackrel{?

Finding mistakes in one-step equations. Solve Equations Using the Division and Multiplication Properties of Equality. Checking the answers for reasonableness will also be practiced.Hook students by explaining that knowing one fact, either multiplication or division, actually allows a student to know all four facts. In the following exercises, solve each equation for the variable using the Division Property of Equality and check the solution. 8.
