Did you know? A truth table is a compact way to describe every possible decision in a simple control rule. G1 Mobile Robotics tuition can help your child connect the table to a robot by naming the inputs, defining what 0 and 1 mean, and explaining the output for each combination.
Start with a paper exercise: a fictional robot may move only when a start request is active and an obstacle-clear signal is active. Define A as the start request, B as obstacle clear, and M as permission to move. The rule is M = A AND B, so only A = 1 and B = 1 gives M = 1.
The 2027 SEC G1 Mobile Robotics syllabus is K130, offered through approved schools. It includes logic gates, truth tables and control circuits. The example here teaches reasoning on paper; actual robot assembly and testing should follow the school’s supervised procedures.

Match the lesson to K130
The official K130 syllabus includes AND, OR and NOT operations, truth tables with up to three inputs, and connections between Boolean expressions and logic circuits.
The immediate learning job is to make the student’s interpretation visible. A child who can recite an AND rule may still struggle to identify which real signal corresponds to each input.
The syllabus also lists block-based coding as not assessed. Do not assume that generic coding enrichment covers the assessed electrical, mechanical and control-circuit knowledge.
Define the signals before filling the table
In our original paper example, 1 means that the named condition is true. A = 1 means a start request is active. B = 1 means the path is reported clear. These meanings are part of the example, not universal sensor conventions.
Ask the student to write the definitions beside the table. Changing B to mean obstacle detected would change the required rule: permission would then require A AND NOT B.
This small change is revealing. If the student keeps the original table despite changing the input meaning, tuition should focus on translation between a condition and its signal.
Explain every row in ordinary language
There are four combinations for two binary inputs. For A,B = 0,0, movement is not permitted. For 0,1, the path is clear but there is no start request. For 1,0, a request exists but the path is not clear. For 1,1, both requirements hold.
The resulting M values are 0, 0, 0 and 1. Ask your child to explain one row without saying only “because it is AND”. The explanation should refer to the two conditions.
Writing all combinations also helps prevent missed cases. Introduce another input only after the two-input relationship is stable, rather than using a larger table to disguise uncertainty.
Distinguish AND, OR and NOT
AND requires both named conditions. OR requires at least one of them. NOT reverses a binary condition. The choice follows the intended behaviour, rather than whichever gate symbol the student remembers most easily.
In a separate fictional indicator task, a warning lamp might turn on when either of two warning signals is active. That OR rule has a different purpose from permission to move.
Use contrasting paper situations so the student chooses a rule and explains it. These simplified examples are not complete real-world safety systems and should not be used as construction instructions.
Check transfer to a fresh decision
After feedback, give another unassessed task with new signal names. Ask the student to define the inputs, state the desired behaviour, choose the logic and explain a table row.
Bring a marked truth-table exercise to a consultation. Ask whether the difficulty is gate knowledge, signal interpretation, listing combinations or linking the expression to a diagram.
Progress is the ability to rebuild the relationship independently. Confirm that any provider has relevant Applied Subject expertise and can coordinate learning with the school’s actual K130 programme.

For parents in Punggol, bring the exact subject title, examination year and recent teacher feedback to a consultation. Ask which difficulty the proposed support will address and how the provider will check independent progress.
For an example of diagnosis and focused 3-pax Mathematics support, see the Secondary 1 Mathematics tutor guide for Clementi. Confirm specialist subject availability and arrangements with the provider before booking.
