We're working on ten more and ten less. Today I took the kids through an activity with three levels. It went rather well.
Each partnership was given a large poster of sorts with twelve boxes and one numeral written in the top box. Their task was to repeatedly add 10 until all boxes were finished. In the end, each poster looked like a column from a 120 chart.
Their second task was to cut their column apart into boxes. Then each partner got to travel around the room to other "puzzles" and put the pieces together in the correct order.
I borrowed the premise from another game for this phase. With the use of a +10 and -10 spinner (which can be seen in the picture below) and counters, the pairs raced to the bottom of their column of numbers.
I love how this activity was easy to prepare. I also love that it progressed in levels. It allowed for lots of practice but in a way that kept things fresh.
