Diben gwneud y meysydd hyn yn drawsgwricwlaidd yw er mwyn i ddysgwyr allu eu defnyddio mewn gwahanol sefyllfaoedd academaidd neu rai go iawn; gallai hynny gynnwys ymarfer eu sgiliau rhifedd drwy ddysgu caneuon pan yn iau, neu gallai olygu dysgu sut i ddatrys problemau a rheoli eu harian mewn perthynas pan yn hŷn.
The purpose of making these areas cross curricular is so that learners can apply them to different academic or real-life situations; from an earlier age that might be practicing their numeracy skills by learning songs or at a later age it might mean learning about how to problem solve and manage their money in a relationship.
