Explore the full colour spectrum, sort by individual colour and by the varying. Colours consists of a pack of 40 flashcards representing 10 colours: red, orange, yellow, green, blue, purple, brown, fuchsia, grey and black. Each colour is made up of a master card, printed both front and back in a solid colour, and three other cards: one in the same shade as the master card, one in a medium shade and one in a lighter tone than the master colour. On the back of these colour scale cards there is a photo of a subject coloured in the same tone as the front. These materials allow children to recognize colours and shades independently. Same colors place on the table only the master cards and those with the colours of the same shade as the master cards. Choose a card, say the name of the colour aloud, for example. This is red!, and invite the child to find the same card. Organize the color shades pick out the colour shade cards (put aside the master cards). Place them on the table by creating small sequences of three cards, one for each colour, placing them from the darkest to the lightest tones. At this point shuffle and put all the cards back on the table (except for the master cards) with the colour side up. Ask the child to recompose the sequences by connecting the cards of one colour at a time from the darkest to the lightest shades. Coloured subjects after forming all the colour sequences, invite the child to turn the cards over, one at a time. In this way they discover that for each shade there is an object on the other side that has that same colour. The represented subjects are purposely photographic to be more easily traceable to reality. At this point we can say the names of the objects aloud. Colour shade games can also be played with the photographic subjects
