Place Value MAB Addition vs Missing Numbers Minds

Little Monkey Apps MAB Addition builds on the previous introductory App, Little Monkey Apps MAB. The App compliments the use of hands on experiences for modelling addition problems using MAB blocks in instances when using real blocks is not practical. MAB or Multibase Arithmetic Blocks are wooden blocks used to help children understand the base ten properties of the numerical system in particular regrouping from one place value column to another. MAB aids students to physically move the blocks to demonstrate their understanding of addition to 9999. =Teaching Module= Contains place value chart, units, longs, flats and blocks, basket for trading and regrouping, random number generator, counter and camera feature. This module is for teachers to create their own learning experiences or for students to use when solving written problems, instead of using real wooden MAB. Students place 'ten' objects in the basket to 'make' or one object to 'break'. 'Make' label appears when ten objects have been placed in the basket and 'Break' label when one object is placed in the basket. =Learn to Trade= Blocks are set out on the floor, to be placed on the place value chart. Use the basket to regroup or trade, then type the answer on the keypad. =No regroup= Use the MAB blocks to complete the addition problem, placing both numbers on the place value chart and then typing the answer on the keypad. Levels of difficulty can be changed the up and down arrow buttons. No regrouping required in this activity as a precursor to the following task. =Regroup= Use the MAB blocks to complete the addition problem, placing both numbers on the place value chart, use the basket to change blocks to represent the correct place value, then type the answer on the keypad. Levels of difficulty can be changed the up and down arrow buttons. Task appears similar to previous challenge but with regrouping in all levels.
