In math this year, the boys learned to measure length in centimeters. The metric rulers they use have centimeters on one edge and millimeters on the other edge, so I have cautioned them to make sure the use the centimeter side when they measure things for school.
Recently during math class, Matthew picked up his ruler and asked 'How long will it be until we can measure things in mama-mias?' * * * * Don't they teach mama-mias in 3rd grade? * * * * *
