Week of Nov. 28th

In Math, we have been reviewing the place value system for reading and writing numbers by distinguishing between the place values of a digit in one-, two-, three and four-digit number and learning the value of each digit. In addition, we have been reading and writing three- and four-digit numbers using words and numerals and understanding the connection between number words, expanded form, and base ten block representations. In this unit, we have also been comparing three-digit numbers using the symbols < and > with base ten blocks and using place value. 

To build on our number sense, we have been regrouping to write numbers as sums of ones, tens, hundreds and thousands in different ways. Having reviewed and developed a stronger sense of numbers and place value, we have now begun to add two, three and four-digit numbers involving the regrouping of ones as tens, tens as hundreds and hundreds as thousands using base ten models and the standard algorithm. In the next two weeks, we will extend this knowledge as it applies to subtracting two,  three and four-digit numbers with and without regrouping and explore a variety of word problems involving addition and subtraction concepts taught in this unit.
