I gave 1 star, pero dapat wala na lang.
Ang nilalaman ng librong ito ay hindi masasagutan ng simpleng estudyante. Kaya inaakala ng karamihan na mahirap ang math ay dahil sa mga librong ganito. Ang
Hindi kailangan ng MA o PhD ng isang tao upang ipaliwanag sa isang grade 3 ang math. Matutunan natin na ibaba ang ating paguunawa sa paguunawa ng isang average na bata at doon natin ibase ang ating libro.
Sana dumaan muna ang mga librong ganito sa DepEd bago gawing textbook.
