📝 Description

Add-UP-Ladder is a mathematics practice game where learners climb through number paths to make the required total. It supports addition, mental calculation, logical path selection, and repeated arithmetic practice.

📋 Instructions

Start from the bottom and move upward through connected number boxes. Choose a path that adds up to the target total shown at the top.

Learning objectives

Keep an accurate running sum along a path.
Check whether a target can be reached before committing to a route.

Concepts and principles

The total of a route is the sum of its selected box values, not merely the final box value.
Equivalent paths may reach the same total even with a different order of addends.

Examples and worked solutions

An illustrative path contains 4, 6 and 3. What target does it meet?: Worked solution: 4 + 6 + 3 = 13; it meets target 13 if those boxes form an allowed connected route.

Guided practice

Follow a connected upward route described by the activity and record each selected number.
Check the running sum against the target before completing the path.

Expected observations and explanations

A path whose sum is too small needs a different combination, not an arbitrary correction to the target.

Assessment questions and answers

Would visiting a box labelled 13 automatically mean the whole path totals 13?: Answer: No. You must add the values along the entire route, according to the game rules.
