Number posters and charts are important resources for teachers. Some posters are standard practice for display in all Early Childhood classes, such as 1-10 charts, shape or colour posters, and 1-100 grids. Some may be be displayed for lessons on specific concepts, such as fraction equivalents, or friends of ten. They can be referred to by both students and teachers during lessons. If wall space is limited, posters of recently introduced concepts can be displayed, while other posters are filed for students to access when they need them (in a display folder perhaps). My posters can be printed in A4 or A3 (using an enlarging option on a photocopier), and when laminated, are like big cards.
