Add+-+Sub+-+Place+Value

A simpler version of a decimal diagnostic

Heaps of Add / Sub stuff from HIBS who were in the first year of SNP schools. Includes worksheets, indexes, "I Can Do" sheets for each stage, planning sheets etc.

- Ideas for Place Value activities that go beyond "what number is in the tens place" (ad nauseum!)

- Place Value for lower ability groups - I found this article on the net and used a couple of ideas from it for my file above, but many seemed to easy for mid/top band. I have given this file to my low-band teachers though in its original form.

(from ISF Nov 07 training) - a good source of questions that trap kids with decimals e.g. "Add ten to 0.15" (they write 0.25 ... or 0.1510 ... or 1.5 .....)

- as per our discussions at the Term 2 Year 1 hui. I have made a set of masters which have the numbers increasing vertically (Iike they would on a graph) and there are also grids for integers to -400.

- a hands-on way for students to understand how many of a given place are in a number, e.g. 123.45 contains 12 tens ... 1234 tenths ... 123 ones ...

- decimal worksheets for students to mark, with deliberate misconceptions included to promote discussion of what decimals are, and are not!

- tests students' understanding of what a decimal looks like under an area model

ADD / SUB / PLACE VALUE TEST - Feilding HS - Heavily influenced by the type of questions Jenn / Ali had in the PNGHS Number Test, but their test covered Mult/Div as well whereas this one is only Add/Sub and Place Value. We made stage 5 = Achieved, stage 6 = Merit, stage 7 = Excellence. We felt there was no point calling stage 8 excellence as the only difference between stage 7-8 is adding / subtracting unrelated fractions e.g. 1 and 2/3 plus 2 and 1/4, and since we haven't taught fractions yet this would have been silly.
