Hi, I am working on the preparation of the "summer book" in mainly Parley-format for my twins and there is plenty of mathematics I cannot create exercises for.<br><br>How/ where could the following be done?<br><br>
1) representing numbers on the abacus<br>2) oder the following numbers according to their value<br>3) additions/substractions/multiplications/divisions with bigger numbers<br>4)<br>stuff like<br><br>1233 x<br> 2=<br>--------<br>
2466 (also the 1233 x 267 multiplications...)<br><br>0,83 x 3 = 2,49 (also represented like above)<br><br>5) divisions in columns like above with and without rest<br><br>6) fill in the blanks<br><br>_ 2 4 -<br>1 1 1 =<br>
----------<br>1 _ 2<br><br>7) resolving step by step: (127x2)+18 = <br>(529+199)-27=<br>(210-105):5=<br>etc.<br><br>8) colour 1/3 of the snails<br>colour the parts of the fraction<br><br>Ok, this seems all so far - the rest can be created with Parley ... geometry is completely missing in that book ... strange ... well, I will come to that bit probably later.<br>
<br>Thanks for any hint.<br><br>Cheers, Sabine<br>
