It is visual only, they do not tell the steps as they make it, but it is easy enough to do and can be paused after each fold for students to do their own. (02:09)

Like any other activity, doing and learning mathematics involves: using and adapting existing knowledge; acquiring and constructing new knowledge through thinking and learning; building up links that enable known t
2.3 ‘English’ as a school subject In official UK curricula, language appears as a curriculum subject under a range of labels. In all four UK countries – England, Northern Ireland, Scotland and Wales – the curricula for the 3–5 years age range (ACCAC, 2000a; DENI, 1997; QCA/DfEE, 2000; SCCC, 1999) include the word ‘language’ in the subject title. In the formal school curriculum, the subject is known as ‘English’ or ‘English Language’ (ACCAC, 2000b; CCEA, 2004; DfEE/QCA, 1999a; SOED, 1991). Wale
1.4 Subject knowledge Subject knowledge is a critical factor at every point in the teaching process: in planning, assessing and diagnosing, task setting, questioning, explaining and giving feedback.
