Here is the link to the activity we did in class yesterday. Just click on the image to go to the web. Remember you have to put the numbers in the triangle to so that each side adds to the same number. Yesterday we saw ways of adding to 9, 10, 11 and 12.
And here’s the link to the bigger triangles we looked at. TRISIDE TOTALS
Thanks to Joan, Roc, Màrius and Àlex for sharing their work with us!
And thanks to Nerea for sending me her work too!
