Knowre’s Walk Me Through feature offers support as you answer questions. This support is interactive and modeled off the way you would work with a teacher or tutor. You can click on the Walk Me Through button when you need help, or you will be taken to it automatically if you answer the question incorrectly.

# Solving Questions

## Walk Me Through

**How it works**

- In the Walk Me Through you will receive guidance that will take you through the steps of solving the problem. You will pay one coin in order to access the support, but can earn it back later by retrying the question
- It’s interactive; you will need to submit answers to questions at each step

- Be sure to open videos if you need them for extra support; you do not need to ‘pay’ coins in order to access the videos
- You may need to ‘pay’ additional coins if you require extra support as you go through the steps of solving the problem
- When you are ready to submit your answer to the original question, minimize the Walk Me Through with the ‘I can solve it now!’ button

- At the end of each problem, you are given the opportunity to ‘Try again” and re-attempt the problem to try to earn 3 coins on that problem

## Entering an answer

Answering fill-in-the-blank questions in Knowre is made easy with a math palette that provides math characters and symbols not available on a regular computer keyboard

**How to use the math palette**

- Knowre’s math palette appears as soon as you place your mouse in the answer input box
- Select the necessary symbols needed to express your answer appropriately
- For answers that require you to answer with sin, cos, or tan, be sure to use the math palette instead of typing the letters using your computer keyboard. Those will be marked as being incorrect
- If there is a symbol that is not found on the math palette, then it is on your keyboard

**Inputting answers**

When inputting responses into the answer field, the rule is to put an answer in the same form as the question. The answer should also be in the most simplified form, unless otherwise specified. Additional tips for answer formatting:

- No double signs unless forced by answer form (e.g. 4-(-2) should be written as 4+2)
- Fractions reduced
- Like terms must be combined
- Evaluate exponents
- No radicals in the denominator (after the skill has been learned)
- Radicals should be reduced (after the skill has been learned)
- No decimals in fractions
- No fractions within fractions
- Repeating decimals must be written with an over bar using as few digits as possible
- For solutions of problem with double signs, parentheses must be used between signs. For example, if asked to use the distributive property simplify the expression -2(x+7), the solution to -2(x+7) can be written as -2x-14 or -2x+(-14), but -2x+-14 cannot be accepted.

## Graphing

Knowre provides many opportunities for students to practice their graphing skills

**How to graph**

- Each graphing problem provides a slightly different version of the graphing palette to help you express your answer appropriately
- If there is a graphing palette on the right side of the page,
**FIRST select the appropriate graph you would like to use and THEN manipulate it on the graph** - If there is no graphing palette on the page, manipulate the graph by clicking and dragging the points
- To clear the graph and start again, click on the line you wish to delete (it will turn green) and click x
- You can modify or delete a line or point when it is green. If a line or point is red, you won’t be able to modify it. Click on the line or point until it turns green, which indicates that it is ready to be modified
- In certain problems you will also be able to change points to open/closed or make lines dotted or solid using the palette made available below the graph

- To express limits, drag the bar underneath the graph
- If run into problems with elements of graphs not moving when clicked or dragged, please refer to our Graphing Troubleshooting Guide.

## Number lines

**How to manipulate the number line**

- Click and drag the point(s) to reposition in the appropriate spot
- Select ‘Change Open/Close’ to modify the point
- Change directions by selecting ‘Change Direction’
