2.1 Hvad er der i æsken
Each hand2mind Mini Student Number Balance Beam Classroom Kit includes:
- 15 Mini Number Balance Beams
- 20 ten-gram hanging weights per balance (total 300 weights for the kit)
- Aktivitetsguide
- Storage Tote

3. Opsætningsvejledning
3.1 Montering
- Unpack all components from the storage tote.
- Identify the red base and the yellow numbered crossbeam.
- Insert the central pivot point of the yellow crossbeam into the slot on the red base. Ensure it is securely seated and can pivot freely.
- The balance has two convenient, non-spill storage compartments on the base for the hanging weights when not in use.

3.2 Kalibrering
The balance beam is designed to be self-correcting. Before use, ensure the beam is level when no weights are attached. If it is not level, gently adjust the base on a flat surface. Calibration clips are included to ensure accuracy; these are typically pre-set but can be adjusted if necessary to achieve a perfectly level balance.

4. Betjeningsvejledning
The number balance beam helps students understand mathematical relationships by physically demonstrating equality, inequality, and basic operations.
4.1 Grundlæggende betjening
- Hang the blue ten-gram weights onto the pegs located beneath the numbered crossbeam.
- Each peg corresponds to a number (1 through 10) on both sides of the central pivot.
- To demonstrate equality, place weights on both sides of the beam until it balances. For example, one weight on peg '5' on one side will balance with one weight on peg '5' on the other side.
- To demonstrate inequality, place weights such that one side is heavier, causing the beam to tilt.

4.2 Exploring Number Concepts
The balance beam can be used to teach a variety of mathematical concepts:
- Addition og subtraktion: Place weights to represent sums (e.g., one weight on '3' and one on '2' on one side will balance with one weight on '5' on the other side).
- Multiplication and Division: Use multiple weights on a single peg or distribute weights to show products (e.g., two weights on '3' will balance with one weight on '6').
- Number Relationships: Visually demonstrate greater than (>), less than (<), and equal to (=).
- Brøker og decimaltal: Utilize the blank value strips (not included in this specific kit description but mentioned in product features) or create custom ones to represent fractional or decimal values.
- Comparing Numbers: Place weights to compare the values of different numbers.

5. Vedligeholdelse
- Rensning: Wipe the balance beams and weights with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals that could damage the plastic.
- Opbevaring: Store all components in the provided storage tote when not in use to prevent loss and damage. Keep in a cool, dry place away from direct sunlight.
- Inspektion: Periodically inspect the balance beams and weights for any signs of wear or damage. Replace any broken or cracked parts to ensure safe and accurate use.
6. Fejlfinding
| Spørgsmål | Mulig årsag | Løsning |
|---|---|---|
| Weights slip off easily | Weights may not be fully seated on the pegs, or excessive manipulation during use. | Ensure weights are firmly pressed onto the pegs. Encourage gentle handling of the balance beam during activities. |
| Balance beam is difficult to calibrate or does not sit level when empty | Uneven surface, or calibration clips require adjustment. | Place the balance on a flat, stable surface. Check and gently adjust the calibration clips if necessary to achieve a level balance. |
| Manglende komponenter | Components were not stored properly or were misplaced. | Always store all parts in the provided storage tote after each use. Contact hand2mind customer support for replacement parts if needed. |
