Mata | Achar | Rang a trí & rang a ceathair | Tomhais | Úsáideann Cian cleas cliste - dhá chruth rialta a dhéanamh as cruth neamhrialta & achar a oibriú amach ón bpointe sin. Tá an rang seo dírithe ar dhaltaí ó rang a trí agus rang a ceathair. Cian has a clever trick - finding two regular shapes in an irregular shape & calculating the area from there. This class is aimed at students from third class and fourth class. Cúla4 Ar Scoil | Ábhar - Mata | Téama - Sa Bhaile
