A study of the use of manipulatives in the assessment of mathematics instruction with ESL Hispanic students. Bilingual Research Journal, 22(2-4), 215-235. I'm including this reference and abstract because it seems like an ideal research article for our group. Unfortunately, the report is written in Spanish only.
Red Rangers are a generation cross from the popular Rhode Island Red & are also known as Columbian Blacktails. These pretty chestnut hen's adapt well to most set up's, especially as backgarden hen's, free-rangers and smallholdings.
Rangers wear dull colour and a metal oakleaf. 1  A Ranger's most essential article of clothing is the mottled green and grey camouflage cloak. Made of tightly woven wool, it offers protection from the weather, and the color makes it easier to remain unseen in the forests of Araluen.
