Students played the game "Finding Neighbors" this week to help develop their understanding of tens and ones place value as well as the relationship between numbers on a 99 chart (this chart goes 0-99). Students physically built a number they spun on a spinner using base ten blocks so they could manipulate the number (above picture shows 74). They then had to find the space that number belongs in on the 99 chart using their knowledge of tens and ones place value. Then they had to find that number's "neighbors" on the 99 chart - the number to the right (+1), the number to the left (-1), the number below (+10), and the number above (-10). This helps them start to develop the ability to mentally add and subtract by one and multiples of ten.
