Compare volume of a and b (equal).Compare volume of e and a (1 to 2).Compare volume of e and / (1 to 3).Compare volume of e to sum of a and b(1 to 4). Compare volume of e to sum of / and d(1 to 5). Compare volume of / to whole frame before any drawerswere put into it (1 to 4). Compare volume of a to volume of large frame (1 to 6). If e holds two of babys dresses, a holds 2 times 2 dresses, or 4 dresses; / holds 3 times 2 dresses, or 6 dresses; the sum of a and b holds 4 times 2 dresses, or 8 dresses; the sum of. MEASUEING: SINGLE UNIT RULERS 125 a, h, and c, holds 6 times 2 dresses, or 12 dresses; the sum ofa and / holds 5 times 2 dresses, or 10 dresses, etc. In this lesson the children handled the rulers 2,4,G,8,10, and one of the papers was 12 long. They have dealtwith this length so often that they know it, even though the12-inch ruler is not in their hands. They saw tliat: 22- 4 62=12 ^/o/- 8 2G=1252=10They also saw the combination, separation and divisionof these number facts. LESSON XXXVA Large Envelope(To hold weaving strips, or braids of cord or raffia untilthey are needed.) Rulers: irl84. Material: 2 sheets manila paper numerical values seen: 11 8 1 1 12 9c A
