This bilingual emergent reader describes the colors and shapes in the state flag of Texas. The 7-page booklet also includes a page for children to draw the state flag as well as the state pledge in both English and Spanish.
The set also includes a Texas/Mexico flag Venn diagram, including cut-and-paste labels, to further reinforce shape and color recognition.
Technical info: The booklet and Venn are both in PDF format, with original, high-resolution, outline images at 300 dpi. Answer keys are also included.
P.S.– The materials in the Texas Collection are the first in what will eventually become a series on the 50 states. Drop me a line if you’re interested in having resources like these for your state.
