In addition, we have also put together a **compilation** of all the Grade 4 to 6 Math and Science lessons, organized by topic. There are two compilations: one for Science and one for Math. So, for example, while addition and subtraction of fractions are taught during Grade 4, and multiplication and division of fractions are taught during Grade 5 in the DepEd timetable, they’re all listed under “Fractions” in the Math compilation. This gives you greater leeway when doing lessons — tackling “advanced” topics if you feel your child or student is ready for them, or spending more time on certain subject matters if you think a deeper or prolonged dive would be much more helpful.
