one more than. one less than. number before. number after. up. down. shake it all about.
Simple worksheet: write the number that comes before and after inside the circle, triangle or hearts.
First number line addition (totals up to 20) jump making worksheet WITH FROGS!
Easy to change the questions, just edit the addition sentence and move the dot on the line and change the start number font colour.
Hope they help children learn addition using a number line.
Good luck from Cambodia.
