    So true and important that we help our students grapple with the multiplicative relationships in place value!

    One thought to consider is when looking for 10 times bigger/smaller, consider switching the language to 1 tenth the size. This will also highlight the reciprocal relationship between “10 times” and “1 tenth” (much like the doubling / halving strategy that emerges in many number talk strings).
