Product Description
1 – This Unit is about solving equations where there are no parentheses and thus no Distributive Property to deal with.

2 – Objects are used again, hopefully with students using variables instead of the whole word for their answers now.

3 –Whatever is on the left side of the equation equals whatever is on the right side. It’s like a big scale. In the case of what is shown in this Kindergarten lesson below, $16 has to be added to the left side of the balance to equal the price of the toy.

4 – Some students just have trouble interpreting what equations mean. For that reason, pretty much all books have students practice writing equations that are to represent some words or a picture. In the second and third lessons of this unit, that idea is taken to another level that is more challenging, having students describe situations which change.

5 – Here is an example of the solving equations: 3N plus or minus something being equal to something. The key is to get rid of what is extra or add back what is missing.
If you have 3N + $5 = $17, then you have $5 too. You take $5 from both sides (to both sides since you have to keep the balance scale balanced) and you have 3N =$12, so each N must equal $4.
If you have 3N - $5 = $7, you’re missing $5. So, you add it back (to both sides since you have to keep the balance scale balanced), get 3N = $12, so N = $4.
