This is a modification of the Helping With Math tasks, "Number Grid Puzzles," https://www.helpingwithmath.com/printables/worksheets/numbers/1nbt4-number-grid-puzzles01.htm. This activity was used with a tier 3 fourth grade intervention math group to help students count by tens in mid-decades and count forward and back by ones. I modified this activity by first having students make observations and note patterns in a hundreds chart; specifically encouraging students to note that counting on by ten ones increased the tens digit by one. Students then modeled this concept with base-ten blocks. Finally, students completed the hundreds chart number puzzles to reinforce this concept and wrote matching equations when a puzzle was solved. For example, "47 = 35 + 12."

Module 4 builds upon Module 2’s work with place value within 20, now focusing on the role of place value in the addition and subtraction of numbers to 40.  Students study, organize, and manipulate numbers within 40.  They compare quantities and begin using the symbols for greater than (>) and less than (<).  Addition and subtraction of tens is another focus of this module as is the use of familiar strategies to add two-digit and single-digit numbers within 40.  Near the end of the module, the focus moves to new ways to represent larger quantities and adding like place value units as students add two-digit numbers.

In this final module of the Grade 1 curriculum, students bring together their learning from Module 1 through Module 5 to learn the most challenging Grade 1 standards and celebrate their progress. As the module opens, students grapple with comparative word problem types. Next, they extend their understanding of and skill with tens and ones to numbers to 100. Students also extend their learning from Module 4 to the numbers to 100 to add and subtract. At the start of the second half of Module 6, students are introduced to nickels and quarters, having already used pennies and dimes in the context of their work with numbers to 40 in Module 4. Students use their knowledge of tens and ones to explore decompositions of the values of coins. The module concludes with fun fluency festivities to celebrate a year's worth of learning.
