# Arithmetic Notebook

## A question type for arithmetic story problems

Story problems (or word problems) are an important part of math education, where students learn to apply mathematics to solve real-world problems. The solution to such problems requires students to go through the following steps:

**Decompose**the problem into partial problems- Write a
**mathematical formulation**of each partial problem - Use math skills to
**solve**the mathematical problems **Interpret**the math results to formulate the answer to the real-world problem.

Compared to procedural math problems, such as solving equations or simplifying expressions, story problems require **higher-order thinking skills**.

Multistep and Arithmetic Notebook question types have built-in support for story problems. Arithmetic Notebook is designed explicitly for arithmetic story problems that do not require variables, formulas, or relations.

## Features

### Notebook

Students can build their solutions **line by line**, using either calculations or natural language. Algebrakit evaluates the calculations and neglects the language.

### Built-in calculator

With the built-in calculator, students do not have to retype the calculations in their calculator. This prevents students from being distracted by procedural tasks and keeps the focus on higher thinking skills.

### Positive feedback

Algebrakit adds a checkmark to each correct line. There is no negative feedback if Algebrakit cannot identify a line as an intermediate step. This stimulates students to use the input field as a notebook, where they are free to express their thoughts.

The progress indicator is an additional feature to assure students they are progressing.

### Conceptual feedback

Students receive conceptual feedback, such as descriptions of what the calculations represent or hints about *what* to calculate (not *how*).

### General Features

Like the other question types, Arithmetic Notebook can run in **assessment mode** to prevent students from seeing evaluation results, hints, or error feedback. This information is available during the review after the student submits the questions or tests.

Arithmetic Notebook also supports **random questions**.
