Dear children

Its time to stand the books up

In rows upon the shelves,

and pack the charts and posters

in neat piles by themselves,

collect the pens and pencils

and put the ink away,

for school time is now over

and every day is for play

so to keep you happily occupied,

we have planned some fun filled and exciting activities for you
