Simon really enjoys math and games.  I’ve found if I casually bring up a “game” that involves some math and we do it together I can get him to practice a concept for a while.  I found this post on Pinterest and thought I could make some of the materials easily myself.  We rolled a die with numbers 0-12 on it.  Each number he rolled was one number in a 4 or 5 digit number he was creating.  When all the blanks were filled he would read off the number.  Next he would take the 1,000, 100, 10 and 1 cards and put the correct amount underneath.  We took turns to see who could roll a bigger number.  Then at the end I put some of the place cards under the blanks and asked him to fill in the actual number.  It worked well both ways.  ps. see if you can catch the photo bomber fresh from his bath 🙂
