Academic Intervention Service with Mrs. Weitz

In AIS (“Academic Intervention Service”) Math we meet in small groups to work on strategies and skills that will help build proficiency in mathematics. AIS Math aims to targets the foundational math concepts necessary for success in the classroom. We use an array of hands-on methods and manipulatives.

Students are selected based on a combination of factors including teacher recommendation and assessments. Our assessments are ongoing, therefore our math groups may change throughout the school year.

Grade 1 Overview

In Grade 1, instructional time should focus on three areas: (1) developing understanding of addition, subtraction, and strategies for addition and subtraction within 20; (2) developing understanding of whole number relationships and place value, including grouping in tens and ones; and (3) developing understanding of linear measurement and measuring lengths as iterating length units.

  • Use addition and subtraction within 20 to solve one step word problems involving situations of adding to, taking from, putting together, taking apart, and/or comparing, with unknowns in all positions.
  • Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20.
  •  Apply properties of operations as strategies to add and subtract.
  • Understand subtraction as an unknown-addend problem within 20
  • Relate counting to addition and subtraction.
  • Add and subtract within 20 using strategies such as: counting on, making ten, decomposing a number leading to a ten, using the relationship between addition and subtraction and creating equivalent but easier or known sums.
  • Fluently add and subtract within 10.
  • Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false.
  • Determine the unknown whole number in an addition or subtraction equation with the unknown in all positions.
  • Count to 120, starting at any number less than 120. In this range, read and write numerals and represent a number of objects with a written numeral.
  • . Understand that the two digits of a two-digit number represent amounts of tens and ones.
    • a. Understand 10 can be thought of as a bundle of ten ones, called a "ten".
    • b. Understand the numbers from 11 to 19 are composed of a ten and one, two, three, four, five, six, seven, eight, or nine ones.
    • c. Understand the numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 refer to one, two, three, four, five, six, seven, eight, or nine tens (and 0 ones).
  • Compare two two-digit numbers based on meanings of the tens and ones digits, recording the results of comparisons with the symbols >, =, and <.
